Butadiene rubber br9000

When purchasing BR9000, you must prioritize the Cis-1,4 content, which should typically be above 96% to ensure high elasticity and wear resistance. Additionally, verify the Mooney Viscosity (ML 1+4 at 100°C), which usually ranges between 40 and 50 for standard BR9000. Other critical parameters include volatile matter (<0.75%), ash content (<0.3%), and tensile strength, as these directly impact the durability of the final rubber compound.

BR9000 is a high-performance synthetic rubber primarily used in the tire industry for tread, sidewalls, and carcasses due to its excellent low-temperature flexibility and abrasion resistance. It is also widely utilized in technical rubber goods such as conveyor belts, shoe soles, hoses, and gaskets. Its ability to be blended with Natural Rubber (NR) or Styrene Butadiene Rubber (SBR) makes it ideal for products requiring high resilience and low heat build-up.

Suppliers should ideally hold ISO 9001 for quality management and ISO 14001 for environmental standards. For specific applications, ensure the product meets REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulations if exporting to the EU. Request a Certificate of Analysis (COA) for every batch to confirm that the chemical composition aligns with international industrial standards like ASTM D-series for rubber testing.

BR9000 is typically produced using a Nickel-based catalyst system (Ni-catalyst), which results in a high-cis structure. This specific technology provides the rubber with superior fatigue resistance and low rolling resistance. Buyers should confirm the catalyst type with the manufacturer, as different catalysts (like Cobalt or Neodymium) can alter the molecular weight distribution and processing characteristics.

The main risks include quality inconsistency between batches and fluctuations in raw material prices (linked to crude oil). To mitigate these, always request a pre-shipment sample for lab testing and use third-party inspection services (like SGS or Intertek) to verify the cargo at the loading port. For transaction security, utilize Trade Assurance services on Made-in-China.com to ensure payment is only released upon proof of shipment.

BR9000 is usually shipped in 35kg bales, wrapped in polyethylene film and packed in wooden crates or metal boxes. It is vital to ensure the shipping container is cool, dry, and well-ventilated, away from direct sunlight and heat sources to prevent cold flow or degradation. Ensure the supplier provides a Material Safety Data Sheet (MSDS) and follows IMDG codes if the specific grade is classified for maritime transport.

Since BR9000 is a commodity, pricing is highly sensitive to volume. Negotiate based on tiered pricing (e.g., 20ft container vs. 100 tons). Professional buyers should aim for FOB (Free On Board) terms to maintain control over freight costs, or CIF (Cost, Insurance, and Freight) if they prefer the supplier to handle the complexities of marine insurance. Always clarify the lead time, which typically ranges from 15 to 30 days depending on production cycles.

Essential documents include the Commercial Invoice, Packing List, Bill of Lading (B/L), and Certificate of Origin. Because BR9000 is a chemical product, a Technical Data Sheet (TDS) and MSDS are mandatory for customs declaration and safety inspections. Check for any anti-dumping duties applicable to synthetic rubber in your specific country to avoid unexpected costs at the border.
