Polybutadiene Rubber (PBR)

Polybutadiene Rubber (PBR)

Polybutadiene Rubber (PBR) is produced by solution polymerization process, has very high elasticity and degree of resistance to dynamic stress, and retains these properties even at extremely low temperatures. Blending natural rubber or styrene-butadiene rubber with PBR improves the abrasion resistance, crack resistance and heat build-up under dynamic load.

Styrene-Butadiene Rubber (SBR)

Styrene-Butadiene Rubber is produced by a technology of cold emulsion copolymerization based on soaps of rosin and fatty acids and contains 23.5% of chemically bonded styrene. It is coagulated by a system of acid and synthetic coagulant. SBR has very good properties such as process ability, abrasion resistance, less tendency to scorching processing. More than half of the world production of E-SBR is used principally in general-purpose tires.
