PBR Reliance Cisamer 1220

Polybutadiene rubber is a synthetic rubber derived from the polymerization of butadiene, a hydrocarbon compound. It is known for its excellent elasticity and low-temperature properties, making it a popular choice in various industrial and consumer applications. Cisamer 1220 is produced using a cobalt catalyst based production process. It is an international quality product, with high cis content, has high elasticity and is resistant to dynamic stress, thus ensuring longer product durability. It exhibits low rolling resistance, better abrasion resistance.
