Sbr price manufacturers

When sourcing SBR, you must focus on the Styrene content (typically 23.5%), Mooney Viscosity (usually ML 1+4 at 100°C), and the emulsion type (e.g., 1502 for light colors or 1712 for oil-extended). These factors directly impact the tensile strength, abrasion resistance, and processing cost. Always request a Certificate of Analysis (COA) to ensure the batch meets international standards like ASTM D3185.

The price varies significantly between Oil-Extended SBR (OE-SBR) and Non-Oil-Extended SBR. OE-SBR is generally cheaper per ton but may increase shipping costs due to weight. For high-end applications like automotive tires or industrial belts, investing in Solution SBR (S-SBR) offers better rolling resistance and wet grip, providing higher long-term value despite a higher initial purchase price compared to Emulsion SBR (E-SBR).

For the EU market, products must be REACH compliant to ensure no hazardous chemicals are present. For US-bound goods, check for TSCA (Toxic Substances Control Act) compliance. If the SBR is used for food-grade seals or medical devices, it must meet FDA 21 CFR 177.2600 regulations. Ensure the supplier provides Material Safety Data Sheets (MSDS) in the destination country's language.

Request samples for Shore A Hardness testing and Elongation at Break analysis. For industrial use, perform an Aging Test (70 hours at 100°C) to check for changes in physical properties. Reliable suppliers on Made-in-China.com often provide third-party inspection reports from agencies like SGS or Intertek to validate these performance benchmarks before bulk shipment.

SBR prices are highly sensitive to crude oil fluctuations and butadiene monomer costs. To mitigate risk, consider long-term contracts with price adjustment formulas or utilize hedging strategies. Monitoring the upstream petrochemical market trends is essential for timing your bulk purchases effectively.

Focus on volume-based discounts; typically, orders exceeding 20 tons (a full container load) can secure a 5-10% discount. Negotiate for flexible payment terms such as L/C (Letter of Credit) or T/T with a 30% deposit and 70% against the Bill of Lading. Always clarify the Incoterms (FOB vs. CIF) to avoid hidden logistics costs.

SBR should be shipped in UV-protected, moisture-proof packaging (usually 35kg bales in wooden crates or metal boxes). Ensure the containers are kept away from heat sources and direct sunlight during transit to prevent premature vulcanization or degradation. Verify that the supplier uses anti-blocking agents to prevent the rubber bales from sticking together during long-distance sea freight.

Utilize the Secured Trading services provided by Made-in-China.com to protect your payment until delivery is confirmed. Conduct a factory audit or hire a local agent to verify the supplier's production capacity and environmental permits. Avoid suppliers who refuse to provide traceable batch numbers or those with prices significantly below the global market average, as this often indicates sub-standard recycled content.
