SBR 1712

Styrene-Butadiene Rubber “CSR 1712” 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 and extended with 37.5 parts highly aromatic oil. It is coagulated by a system of acid and synthetic coagulant. The rubber is protected by stabilizer system. Raw materials for this product are carefully chosen for the best physical properties.
SBR 1712 has very good properties such as processability, abrasion resistance, less tendency to scorching processing.
APPLICATION
Application possibilities for TSBR 1712 include tire and mechanical goods compounds where color and staining are not decisive factors.
