Sbr 1502 rubber price manufacturers

When sourcing SBR 1502, you must prioritize the Mooney Viscosity (ML 1+4 at 100°C), which should typically fall between 46 and 58 units to ensure proper processability. Additionally, verify the Bound Styrene content (23.5% nominal) and Organic Acid content (5-7%). High-quality SBR 1502 should have Ash content below 0.5% and Volatile Matter under 0.75% to prevent defects during the vulcanization process.

SBR 1502 is a non-staining, cold-polymerized rubber widely used in tire treads, shoe soles, conveyor belts, and molded rubber goods. If your application involves food-grade contact or specific environmental sensitivities, you must ensure the supplier complies with REACH and RoHS standards. For automotive components, check for ISO/TS 16949 certification to guarantee the material meets rigorous durability and safety benchmarks.

The price of SBR 1502 is highly sensitive to the cost of raw materials (Butadiene and Styrene monomers), which are derived from crude oil. Buyers should monitor upstream petroleum trends and seasonal demand from the tire industry. To optimize costs, consider bulk procurement (FCL - Full Container Load) to reduce the per-ton logistics cost, and look for suppliers on Made-in-China.com who offer tiered pricing based on annual volume commitments.

Request a Certificate of Analysis (COA) for every batch and perform a rheometer test to evaluate the cure rate and torque. It is highly recommended to order a sample of 5-10kg for trial compounding in your specific formulation. Professional buyers should also check the tensile strength (min 20 MPa) and elongation at break (min 400%) after vulcanization to ensure the rubber meets the mechanical requirements of the end product.

The main risks include quality inconsistency between batches and moisture damage during sea transit. To mitigate these, use Third-Party Inspection services (like SGS or Intertek) to verify the cargo before loading. Ensure the rubber is packed in standard 35kg bales wrapped in polyethylene film and secured in wooden crates or metal pallets to prevent contamination and deformation during long-haul shipping.

Focus negotiations on price formulas linked to market indices (like ICIS or Platts) rather than fixed prices to account for raw material volatility. Inquire about payment terms such as L/C (Letter of Credit) or T/T with a deposit, and leverage the competitive landscape on Made-in-China.com by requesting quotes from at least 3-5 verified 'Diamond Members' to establish a market baseline.

Always conduct transactions through secure payment channels and verify the supplier's Business License and Export Permits. Ensure the Bill of Lading (B/L), Commercial Invoice, and Packing List are meticulously prepared to avoid customs delays. For added security, prioritize suppliers who have undergone on-site factory audits and have a proven track record of exporting to your specific region.

SBR 1502 is typically shipped in 20ft containers, which can hold approximately 20-21 metric tons. Use FOB (Free On Board) terms if you have a reliable freight forwarder to control costs, or CIF (Cost, Insurance, and Freight) if you prefer the supplier to handle the logistics risk. Ensure the shipping line provides adequate free time at the destination port (typically 14 days) to avoid demurrage charges during customs clearance.
