Industrial Production Observations
Ethylene tar forms through side-reactions during high-severity steam cracking. Key feedstocks include naphtha, light hydrocarbons, and associated refinery distillates. The process route at Shanghai dictates aromatic ring growth and heavy residue content, leading to differences in viscosity, flash point, and downstream handling profile.
Grade and Application Dependency
Specifications change based on target market — for road binder, residual carbon and asphaltene content matters more, while for chemical feedstock, phenolic and naphthalene fractions drive value. Applications requiring tight boiling range or low sulfur require process modifications, often including secondary distillation or hydrotreatment offsite.
Effect of Properties on Formulation and Storage
Material consistency through controlled feeding and tight process monitoring gives repeatable batch characteristics. Downstream formulation often reacts to seasonal variation in input streams. Higher aromatic content drives storage stabilization need, with potential stratification if left undisturbed for long periods. Storage tanks use heating coils or agitation to maintain pumpability, tailored to viscosity at local ambient temperature.
Manufacturing Logic and Quality Management
Raw materials are selected with a view to minimizing sulfur and metal contamination. Tar output control uses distillation cut points set by quality control for each campaign. Impurities typically arise from process upsets, mis-stripping, or carryover from upstream units. Inline monitoring tracks density and boiling range, backed by periodic batch composite analyses for total aromatics, softening point, and heavy metal residues. Consistency is managed through recycle of off-spec fractions and blending strategies. Release criterion hinges on end-use specification — binder grades place weight on penetration and residue analysis, whereas chemical feedstocks demand detailed hydrocarbon speciation and sulfur reporting.
Technical Properties, Manufacturing Process & Safety Guidelines of Sinopec Shanghai Petrochemical Ethylene Tar
Physical & Chemical Properties
Physical State & Appearance
Ethylene tar in production typically appears as a viscous, dark brown to black semi-liquid or solid, depending on temperature and storage. Visual and olfactory properties such as coloration and odor intensity relate directly to the degree of condensation and the aromatic content, both of which are influenced by the grade and feedstock variability. Lower-melting fractions are softer, more fluid, and more pungent, which can influence pipeline or pump transfer. Melting and boiling points shift significantly with compositional mix and are not fixed reference points; blending history and downstream processing dictate consistency. Flash point is monitored to manage storage and fire safety, with engineering controls applied where volatility is elevated. Density measurements depend on the aromatic-to-aliphatic ratio and residuals from upstream cracking operations.
Chemical Stability & Reactivity
Without air exclusion, ethylene tar tends to oxidize and form gum. Some batches show phase separation or thickening under slow-moving or stagnant storage, mainly where temperature swings or ingress of water occurs—this impacts transfer and blending reliability. Resinification accelerates with prolonged storage and metal contamination. Grade requirements for downstream distillation call for control of peroxide-forming tendencies and minimal unsaturated fractions. Highly unsaturated tars react vigorously with chlorinating agents or strong oxidizers, so segregation from reactive chemicals remains fundamental in plant practice.
Solubility & Solution Preparation
Solubility character varies widely across grades. Aromatic fractions dissolve more readily in toluene, xylene, and similar aromatics; less so in aliphatics. Higher molecular weight residues resist solubilization, limiting applicability where clear solutions are required. Batch-to-batch blending requires heating and agitation to ensure uniformity before downstream use. Water solubility is negligible, which gives rise to interface handling during tank transfers and cleanouts.
Technical Specifications & Quality Parameters
Specification Table by Grade
Specifications for ethylene tar are set by end-user application and governed by downstream process type (e.g., carbon black feedstock, fuel blending, or pitch production). Key parameters—sulfur, ash, quinoline insolubles, water, and specific gravity—are tailored for each batch. Typical values depend on grade and application requirements, and the specification envelope tightens where tars feed critical downstream reactors.
Impurity Profile & Limits
In industrial scenarios, impurity profiles depend on cracker feedstock quality, process severity, and separator performance. Sulfur and ash arise from feed and process corrosion, while water ingress correlates with condensation handling. We monitor metals (vanadium, nickel) where refiner blendstock integration is practiced. Impurity limits are set according to customer needs and regulatory standards, not generically defined across all grades.
Test Methods & Standards
Standard methods, such as distillation range determination, density by pycnometry, and quinoline insoluble quantification, underpin our internal QC. The adopted method may adjust for customer, sector, and export requirement, often referenced to both Chinese and international standardization depending on end use.
Preparation Methods & Manufacturing Process
Raw Materials & Sourcing
Ethylene tar arises as a byproduct from steam cracking light hydrocarbons. Feedstock quality and composition determine the tar’s ultimate boiling profile and functionality. We source only from controlled ethylene unit tar fractions, discarding process bleed or off-spec output to maintain downstream processing safety and consistency. Raw material compatibility with receiver units (e.g., pitch, carbon black) drives initial selection.
Synthesis Route & Reaction Mechanism
The process extracts tars from cracked gas through staged condensation and separation. Fractionation units isolate the ethylene tar cut, and the precise cut temperature and rate depend on the targeted aromaticity and viscosity. Adjustment of cooling profiles alters the hydrocarbon distribution, directly impacting physicochemical properties. Deeper cracking or higher residence yields more reactive, higher molecular weight fractions, raising downstream handling challenges.
Process Control & Purification
Process integrity relies on temperature and residence control to avoid polymerization and ensure consistent recovery. Purification takes the form of gravity settling, filtration, and de-watering. Batch consistency monitoring occurs via real-time viscosity and density probes, with laboratory checks on distillation range and sulfur content. Major process risks stem from fouling and handling unstable fractions, so periodic purge and tank farm rotation form part of routine operations.
Quality Control & Batch Release
Release criteria align with contract and technical service commitments. Laboratory analysis confirms physical properties and impurity levels. The final release standard is subject to internal quality control criteria and customer requirements, with retained reference samples for traceability and troubleshooting. Any off-spec batch diverts to low-value use or internal energy recovery to avoid downstream contamination risk.
Chemical Reactions & Modification Potential
Typical Reactions
Ethylene tar undergoes sulfonation, alkylation, and controlled oxidation for specialty product manufacture, including resin, fuel additivation, or modified pitches. Reactivity alters sharply with the unsaturated/aromatic content, which is again process- and grade-dependent. Some applications seek hydrogenation to stabilize and remove reactive side groups, while others accept high reactivity to facilitate further chemical conversion.
Reaction Conditions
Reaction settings such as catalyst loading, temperature, and solvent choice follow downstream process integration needs. Exothermicity and byproduct management require careful pilot review before scale-up. For aromatic enrichment or de-ashing, batch-specific adaptation is often needed, avoiding blanket process recipes.
Derivatives & Downstream Products
Major derivatives include carbon black feedstock, pitch, heavy oil blends, and chemical intermediates for resin and binder manufacture. Suitability for transformation depends on fraction volatility, impurity content, and physical flow characteristics as set by the tar's production campaign.
Storage & Shelf Life
Storage Conditions
Storage involves heated tanks (to prevent solidification and settling) and floating roof designs to minimize oxidation and water ingress. Strict temperature monitoring prevents thickening or cold flow issues. Tars destined for blending require periodic recirculation for homogeneity. Moisture entry intensifies corrosion and emulsification risk, so dehumidified nitrogen blanketing is used in sensitive applications. Sensitivity to light is low relative to other petrochemicals, but long-term storage under direct sunlight still impacts top-layer quality.
Container Compatibility
Carbon steel and specific internally-coated tank designs function well for stabilized tars. Where metals or process carryover threaten batch purity, lined containers are deployed, with regular maintenance needed due to the tar’s potential for fouling and residue buildup.
Shelf Life & Degradation Signs
Shelf life hinges on temperature, agitation, and exclusion of air and water. Degradation shows up as thickening, phase separation, sludge or gum. The presence of such signs requires remediation—either filtration, blending, or disposal in accordance with operational and customer quality protocols.
Safety & Toxicity Profile
GHS Classification
Hazard classification depends on both flash point and aromatic content. Most grades qualify as combustible and possibly suspected carcinogens due to PAH content, subject to regulatory review. Firm classification follows technical and regulatory data on each production run; broad statements are avoided due to compositional variability.
Hazard & Precautionary Statements
Contact with skin and inhalation of vapors should be minimized due to irritation and chronic toxicity concerns. Physical hazards relate directly to combustibility and inhalation of fumes, particularly during heating. Contingency plans focus on thermal incidents and vapor suppression.
Toxicity Data
Toxicological profile ties to PAH and light aromatic content, which varies with process conditions. Chronic health data guide site PPE and industrial hygiene management, rather than a universal value. Any handling guidance provided reflects most stringent customer/industry requirements in force at the time of shipment.
Exposure Limits & Handling
Permissible exposure levels reference occupational health standards for tars, set by compounded naphthalene and benzene fraction presence. Handling guides prioritize ventilation, containment, and fire safety precautions. Operational controls and PPE selection adjust to batch composition, with routine review against latest regulatory and toxicological findings.
Sinopec Shanghai Petrochemical Ethylene Tar Supply Capacity, Commercial Terms & 2026 Price Trend Forecast

Production Capacity & Availability
Ethylene tar stands as a significant byproduct of ethylene cracking operations. Production at our Shanghai facility depends on ethylene throughput, cracker load, and operational intensity. Output volume varies year to year, with shutdown cycles, turnaround schedules, and feedstock quality shifts playing a controlling role. Stable production hinges on regular raw material feed, process optimization, and equipment reliability. Grade differentiation—depending on customer segments—affects how tars are segregated and recovered within the process. High-conversion cracking increases aromatic load and reduces heavier fractions, which influences both quantity and composition of tar available for sale.
Lead Time & MOQ
Lead time correlates directly with batch turnover and downstream allocation. Typical shipment readiness ranges from a few days, for standard grades, to several weeks, if special grade adjustments or additional purification are required. MOQ largely reflects transport economics and storage constraints, with standard lots matching railcar, ISO tank, or bulk tanker sizes depending on destination and contract terms.
Packaging Options
Bulk liquid form remains the dominant format for high-volume buyers, relying on rail, tank truck, or seaborne bulk shipments. Drum, IBC tote, and ISO container options serve smaller or more specialized orders, subject to grade compatibility, handling limitations, and destination-specific labelling or certification requirements. Packaging method selection must reflect both the consistency of the grade and the downstream application, especially for those seeking higher purity or specific viscosity ranges.
Shipping & Payment Terms
Shipping methods and terms—FOB, CIF, ex-works—depend on logistical feasibility, destination infrastructure, and buyer preference. Compliance with international transport regulations, port restrictions, and HS code classifications is non-negotiable. Payment terms reflect buyer standing, volume, and credit assessment; common mechanisms include letter of credit, TT in advance, and open account for established partners with solid payment histories.
Pricing Structure & Influencing Factors
Raw Material Cost Composition & Fluctuation Causes
The main inputs defining ethylene tar cost are naphtha or light hydrocarbon crackers’ operational expenses, energy consumption, and plant-wide maintenance allocation. Feedstock swings—principally volatility in crude oil, naphtha, or ethane—introduce recurring unpredictability. High upstream prices cascade into higher per-tonne costs due to greater opportunity costs and competing outlet economics.
Price differentials between grades reflect differing degrees of purity, polyaromatic content, sulfur levels, water content, and batch uniformity. Higher-grade material supports tighter specifications and requires further separation and verification steps, which adds cost. Certification for export, especially to North America, Europe, or Japan, demands documentation, third-party testing, and at times regulatory registration, all of which alter the delivered netback.
Product Price Difference Explanation: Grade, Purity, Packaging, Certification
Base grade serves industrial burners and coke-oven blending. High-purity streams used as feedstock for carbon black or fine chemicals carry a premium due to additional distillation and impurity control. Packaging exerts a measurable effect: bulk liquid offers cost advantages, while certified drum shipments, especially for regulated markets, involve overhead for inspection, lab analysis, and compliance paperwork. Customs clearance for certain destinations may require material safety evidence or REACH/regional registration, leading to further differentiation in cost structure.

Application Fields & Grade Selection Guide for Sinopec Shanghai Petrochemical Ethylene Tar
Application Fields & Grade Matching Guide
Industry Applications
Ethylene tar from our Shanghai facilities enters applications across carbon black manufacturing, electrode binder pitch, antifouling coatings, and selected road paving formulations. In these sectors, the selection of grade directly affects process stability, pitch performance, residue handling, and compatibility with downstream fillers or reactants.
For carbon black production, properties like softening point, coking value, and ash content draw close attention because these impact both furnace operation and carbon quality. Electrode manufacturers require predictable coking performance and controlled impurity levels to maintain product consistency and electrical properties. For coating binders, both the level of heavies and volatiles determine final film behavior and resistance to separation. In pavement binders, viscosity and compatibility with other hydrocarbon fractions set the application window.
Grade-to-Application Mapping
| Industry Segment | Preferred Grade (Typical) | Key Properties Impacting Use |
|---|---|---|
| Carbon Black Feedstock | Low-ash, high-coking-value grades | High fixed carbon, low metals content, predictable boiling range |
| Electrode Pitch Binder | Controlled softening point, low-volatile grades | Consistent coking/residue profile, minimal heteroatom content |
| Coating & Antifouling Agents | Low-residue, uniform-viscosity grades | Narrow boiling fraction, balanced viscosity, controlled S and N |
| Paving Applications | Flow-modified, blended grades | Rheology under application temperature, residue after simulated aging |
Key Parameters by Application
In carbon black units, softening point and metals content influence both plug rate and product color. Coking value and volatiles content matter most to electrode pitch consumers, impacting baking behavior and structure. Binder-pitch users often request specification on TGA residue, S content, and softening distribution. In road material use, viscosity index, durability after simulated weathering, and cold-flow value dominate grade selection. While many properties overlap, the weight of each in release criteria is application-driven and subject to adjustment based on feedback from end-use experience.
How to Select the Right Grade
Step 1: Define Application
Start with clear identification of the final use. In direct furnace-injection systems for carbon black, focus on feed consistency and predictable block point. Electrode manufacturing requires tighter specification on ash, heavy metals, and softening range. Coating or pavement users need clarity on workability, storage stability, and handling characteristics.
Step 2: Identify Regulatory Requirements
Many applications, especially in coatings and road use, come under regional or application-specific chemical limits. Policy may determine allowable metals, PAH (polycyclic aromatic hydrocarbon), or sulfur content. Domestic and overseas production often face different thresholds. Build these into the initial grade matching step to avoid costly reformulation or compliance issues downstream.
Step 3: Evaluate Purity Needs
Control over feedstock purity arises both from upstream (olefin cracker) operation and downstream purification. Decide early if high purity matters more for your use or if tolerance for heteroatoms and asphaltenes is possible. Greater control over contaminants increases cost and narrows available production runs. For continuous operations, consider acceptance of on-specification blending from separate batches.
Step 4: Consider Volume & Budget
Batch production, continuous delivery, or annual contract supply all depend on realistic volume forecasts and cost alignment. Some specialty grades require extended campaign running or post-cracker fraction distillation. Cost per unit rises with tighter cuts, extensive purification, or lower-run batch sizes. For large users, multi-shipment lot matching and grade blending become key negotiation points.
Step 5: Request Sample for Validation
Process validation remains essential. No amount of laboratory data replaces pilot-scale or in-plant trial for confirming compatibility. Request a representative batch sample, compare measured outcomes against expected performance in your formulation or process route. Feedback on color, coking tendency, or residue pattern drives iterative adjustment, with quality control from both ends ensuring production alignment. Final grade adoption occurs only after internal and external QC sign-off against mutual acceptance criteria.

Industrial FAQ
What is the typical chemical composition and viscosity range of Sinopec Shanghai Petrochemical Ethylene Tar?
Industry Context of Ethylene Tar
Operating at the source of production, our direct experience with ethylene tar spans a range of applications across road paving, waterproofing, and industrial coatings. Ethylene tar results from the pyrolysis of naphtha or other feedstocks during ethylene cracking. As a manufacturer, we manage every step—starting from raw feed selection, through process optimization, to strict quality control. Years of operating our reactors and distillation systems have shown that the right control over feedstock and reactor conditions leads to consistent quality in every lot of ethylene tar.
Key Chemical Characteristics
Our ethylene tar falls under the category of heavy, aromatic-rich hydrocarbons. The typical chemical profile consists of condensed polycyclic aromatic hydrocarbons, various aromatic resins, along with some asphaltenes and paraffinic residues. Molecular weight leans toward the higher end—resulting from substantial cracking and recombination reactions in the ethylene unit. The polyaromatic character imparts the product with distinctive black coloration, strong hydrophobicity, and a characteristic odor. Lab analysis confirms that sulfur and nitrogen compounds remain at moderate concentrations, characteristic of naphtha-based feedstocks in our region.
Our process does not support heavy inclusion of light or volatile organics because the separation columns collect fractions according to spec. Water content stays low thanks to overhead drying in our distillation units, which is critical for storage, handling, and product performance.
Viscosity Range: What to Expect From Our Output
Years in direct production have taught us that viscosity remains a primary concern for usage and transport. Customers in the road and waterproofing sectors rely on viscosity staying within a predictable range for batch blending, pumpability, and uniform application. From our drum taps to bulk tankers, we control viscosity via process temperature, residence time, and fraction blending in post-treatment. Typical kinematic viscosity at 100°C falls within the range of 500–1500 mm2/s, depending on operating mode and batch selection. When production targets a higher softening point, such as for heavy-duty binders, viscosity increases proportionally as resin and asphaltene content rises.
Critical to our downstream users, viscosity checks form part of every factory batch report. Our labs rely on ASTM D445 and D2170 for lot approval, ensuring the finished product flows as expected during asphalt mixing or mastic blending. For customers with specialized binder needs—such as lower viscosity for cold application or higher viscosity for modified bitumen—unique runs with parameter adjustment are available.
The Importance of Consistency and Transparency
Anyone engaged in further formulation or direct use expects minimal deviation batch-to-batch. Because our facilities operate at scale and under close process control, we provide a product where composition and viscosity rarely stray from the published ranges. Direct feedback from end-users has shown that reliable performance reduces rework, prevents handling issues, and extends service life when ethylene tar finds use in infrastructure or industrial applications.
Our technical team offers detailed laboratory data and product history on request to support customer formulations or compliance documentation. In addition, our plant allows for customer audits and joint review of production or inspection records for contractual projects. Quality assurance stands as a core pillar of our overall production philosophy.

We closely monitor these variables in real time. This approach guarantees each shipment meets the technical thresholds our buyers expect, especially for applications where process variability can impact performance or compliance.

Our standard packaging formats support bulk delivery, with availability in road tankers, ISO tank containers, and railcar loads depending on customer facility requirements. Drums and intermediate bulk containers may be arranged for smaller-scale or specialty orders, though our primary mode remains bulk liquid. Occupational health and environmental management guide our internal handling protocols during filling and transport, with care given to proper temperature control and offloading procedures.
Minimum Order Quantities in Practice
Industrial consumption drives our minimum order quantity requirements. For bulk ethylene tar, the floor for a standard order typically aligns with a full truckload—approximately 20 metric tons. For export, a minimum ISO tank container load meets most international shipment standards. Maintaining this threshold allows us to optimize operational efficiency from pipeline transfer through to logistics and reduces unnecessary handling risks associated with partial loads.
Our technical staff understands some customers may run pilot programs or trial new formulations. In such cases, we make a concerted effort to review and discuss feasible smaller-batch delivery, if aligned with operational safety and cost structures. Long-term supply agreements can include flexible loading intervals or storage options, which helps customers better synchronize supply chain planning.
Collaborative Solutions to Sourcing Challenges
Bulk ethylene tar procurement sometimes presents challenges when customers modernize facilities or shift seasonal demand. To address these periods, our production planners coordinate with customers’ purchasing teams, setting forward delivery schedules and inventory transfer arrangements. This open communication helps avoid supply interruptions caused by cracker maintenance or seasonal utility constraints.
Our in-house technical support provides detailed product data sheets, shipment traceability data, and assistance with regulatory documentation where needed. This transparency builds mutual trust and accountability in the supply chain. As we see more refineries upgrading their integration and capacity, we continue investing in both multiproduct logistics and digital inventory tracking to ensure steady, reliable volume—no matter the purchasing cycle.
Our production philosophy centers around building long-term industrial partnerships. Reliability in both volume and technical profile is not negotiable for ethylene tar users downstream. By maintaining consistent minimum order policies, investing in bulk logistics, and adapting to sector-specific off-take requirements, we support customers’ success as much as our own.
Are there specific international shipping regulations or hazardous materials classifications that apply to the transportation of this product?
Moving chemicals across borders means taking regulations and safety standards seriously. We follow international guidelines for shipping, and every shipment starts with a review of the latest regulations and a full hazard assessment. Our product falls under specific hazardous materials classifications, and our teams have learned that small oversights at the packaging and documentation stage can cause costly delays.
We regularly work with the United Nations’ Model Regulations, the IMDG (International Maritime Dangerous Goods) Code for ocean freight, and the IATA Dangerous Goods Regulations for air transport. Each of these bodies reviews substances for physical hazards, environmental impact, and proper declaration. Regulatory authorities specify if a chemical requires a UN number, hazard label, and safety documentation. Many specialty chemicals—ours included—appear on the Dangerous Goods List, so every drum and container must be packaged and labeled according to these strict rules.
Shipping documentation demands accuracy. A slight error on a shipping label or a missing hazard diamond can create serious delays at ports, or, worse, lead to fines or confiscation. We generate safety data sheets that match both the local requirements of the loading port and the destination country. Every label includes the proper hazard pictogram, UN number, and precautionary statements in compliance with GHS (Globally Harmonized System) standards. This approach reduces the risk of miscommunication during customs inspection.
Hazard Communication and Packaging Integrity
Our technical support team reviews every batch for packaging integrity. For marine shipments, our chemical products ship in UN-certified drums or totes with tamper-proof sealing. Each unit passes drop and stacking tests before leaving the factory. We never compromise on packaging quality, because part of compliance is simply making sure that containers remain leak-free through the rigors of transshipment, rail, and truck transport.
Every load receives proper segregation instructions to prevent incompatibles from sharing a container. We coordinate with logistics partners on stowage and ensure that our declared cargo never travels alongside goods with potential for dangerous interaction. Our own compliance audits flag weaknesses before local port inspectors do. By the time the product leaves the facility, both the physical goods and the required documentation have passed a standardized review.
Continuous Monitoring and Proactive Compliance
International shipping regulations evolve. We track updates in the IMDG Code, changes in classification criteria, and amendments to environmental requirements. Our regulatory affairs unit communicates regularly with the export team, so changes reach the shop floor before they affect shipping procedures. We maintain training programs for our shipping staff to catch regulatory shifts, not only at the country of origin but in all major transit and destination markets.
We see the real-world consequences when rules are overlooked. Ports reject improperly labeled containers. Incorrect hazard declarations lead to disruptions that every manufacturer prefers to avoid. Our approach focuses on prevention—ensuring that our customers never face unnecessary risk from regulatory non-compliance. We invest in compliance because it protects public safety and business continuity for everyone involved in the chemical supply chain.
