Styrene-Butadiene Rubber (SBR)
Description
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.
