Synthetic rubber sbr 1502 manufacturers

SBR 1502 is a cold-polymerized, non-staining emulsion styrene-butadiene rubber. You must verify the Mooney Viscosity (typically ML 1+4 at 100°C: 46-58), Bound Styrene content (23.5% nominal), and Ash content (<0.5%). Ensure the supplier provides a COA (Certificate of Analysis) for every batch to guarantee consistency in processing and physical properties of the final vulcanizate.

Due to its excellent abrasion resistance and aging stability, it is widely used in tire treads, shoe soles, light-colored mechanical goods, and floor mats. Its non-staining property makes it ideal for white sidewalls or any rubber product where color migration must be avoided. It is also a preferred choice for adhesives and industrial hoses.

Suppliers should adhere to ISO 9001 for quality management and ISO 14001 for environmental standards. For specific markets, ensure compliance with REACH (EU) or TSCA (USA) regulations regarding chemical substances. If the rubber is used for food-contact items or toys, verify it meets FDA 21 CFR 177.2600 or EN71-3 standards.

SBR 1502 is non-oil extended, whereas SBR 1712 contains highly aromatic oil. While SBR 1502 has a higher raw material cost per ton, it offers superior tensile strength and modulus without the risk of oil leaching. For high-end light-colored products, SBR 1502 is the most economically viable long-term choice to prevent product degradation and staining.

The main risks include price volatility due to crude oil fluctuations and moisture contamination during sea transit. Always insist on palletized packaging with moisture-proof PE film wrapping. Furthermore, verify the HS Code (typically 4002.19) to avoid customs delays or incorrect duty applications in your destination country.

Focus on volume-based pricing tiers; for orders exceeding 20 tons (a full 20ft FCL), you should aim for a 3-5% discount off the spot price. Request a sample for lab testing (2-5kg) before committing to a full container. Discuss payment terms like L/C (Letter of Credit) or T/T with a 30% deposit, ensuring the balance is paid against the Bill of Lading (B/L).

SBR 1502 should be stored in a cool, dry, and well-ventilated warehouse away from direct sunlight and heat sources to prevent premature cross-linking or 'scorching.' During shipping, ensure the container is clean and free of odors, as rubber can absorb volatile organic compounds which may affect its chemical purity.
