SBR 1502 is produced by famous chemical plants in the world and have a wide range of uses in people's lives.
Styrene-butadiene rubbers are produced by a technology of cold emulsion copolymerization and are coagulated by a system of acid and synthetic coagulant. Some grades are solid and some are modified by extender oils. Styrene-butadiene rubbers are stabilized by staining or non-staining antioxidants. Styrene-butadiene rubbers are appropriate for rubber compounds used in the production of car tires and inner tubes, conveyor belts, footwear, cables, hosepipes and various technical rubber articles. Non-staining grades of rubber are appropriate for compounds used in the production of floor coverings, bicycle tires, footwear, children toys, cables, hosepipes and various rubber articles having light color shades.
