TJPC 1712

1 product description

Styrene-Butadiene Rubber "TJPC 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.

2 applications

Application possibilities for TJPC 1712 include tire and mechanical goods compounds where color and staining are not decisive factors.CHARACTERSTICS
