Styrene-Butadiene Rubber is produced by a technology of cold emulsion copolymerization based on soaps of resin and fatty acids and contains 23.5% of chemically bounded 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.
The products are available in clear or oil extended grades, with staining or non staining antioxidant. Non-Oil Extended Styrene-Butadiene Rubber
