Products Description
Polybutadiene Rubber PBR 1220/BR 9000
Polybutadiene Rubber PBR1220 is a high cis polybutadiene rubber produced using neodymium catalyst technology. It is supplied as a light-colored solid rubber bale and is insoluble in water. With a cis-1,4 content typically above 96% and a very low glass transition temperature, PBR1220 provides outstanding abrasion resistance, resilience, tear strength and low-temperature flexibility after vulcanization. It is widely used in high-performance tire compounds, conveyor belts, shoe soles and other dynamic rubber products where low rolling resistance and long service life are required.
Polybutadiene Rubber BR9000 is a high cis polybutadiene rubber produced by solution polymerization of butadiene using a nickel-based catalyst system. Compared with natural rubber, BR9000 offers improved heat aging resistance and stable processing performance, making it suitable for tires, industrial rubber products, footwear and various molded rubber components.
PBR1200/BR9000 uses:
Polybutadiene Rubber PBR 1220/BR 9000 is used in the manufacture of tire treads, various hoses, tapes, seals, shoe soles and other rubber products.
- Tire Industry: Passenger car tires, heavy-duty OTR/mining tire tread & sidewall, lower rolling resistance
- Footwear: Sports shoe soles, safety work boot bottoms, anti-slip wear-resistant formula
- Industrial Rubber: Conveyor belts, transmission hoses, vibration dampers, gaskets & seals
- Other Fields: Golf ball cores, rubber rollers, plastic impact modifier, cable insulation

FAQ
Q1: What's the difference between PBR1220 and BR9000?
A: PBR1220 neodymium catalyst with higher cis content, better cold & wear resistance for high-performance tires; BR9000 nickel type, more cost-effective for general rubber products.
Q2: Can you provide free samples?
A: Yes, we support small sample testing for factory formula verification.
Q3: Is polybutadiene rubber classified as a hazardous material?
A: No. Polybutadiene rubber is generally transported as a non-hazardous material under normal transportation regulations and does not require hazardous goods handling for standard sea or land shipment.
Q4: What industries commonly use high cis polybutadiene rubber?
A: High cis polybutadiene rubber is widely used in passenger and truck tires, mining tires, sports shoe soles, conveyor belts, rubber hoses, vibration isolation components, golf ball cores, rubber rollers, and engineering rubber products requiring high wear resistance and resilience.
Q5: What documents can you provide with each shipment?
A: We provide a complete export documentation package, including COA, MSDS (SDS), TDS, Packing List, Commercial Invoice, and Certificate of Origin upon request to facilitate customs clearance and quality verification.
Q6: How do I choose between PBR1220 and BR9000?
A: If your application requires maximum abrasion resistance, low rolling resistance, and superior low-temperature performance, PBR1220 is generally the preferred choice. If you are looking for reliable processing performance and a more economical solution for general rubber goods, BR9000 is an excellent option.
