CHARACTERSTICS: Styrene-Butadiene Rubber "TJPC 1502" 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 and stabilized by a non-staining antioxidant. TJPC 1502 has very good properties such as processability, abrasion resistance, less tendency to scorching. APPLICATION: TJPC 1502 is appropriate for rubber compounds used in the production of tire sidewall, floor coverings, bicycle tires, footwear, children toys, cables, hosepipes and various rubber articles having light color shades.
