- SBR 1507
Oil-Based:
- SBR 1712
- SBR 1723
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.
The products are available in clear or oil-extended grades, with staining or non-staining antioxidant.
Packing
