Solprene® 1430

High molecular weight linear random -block 1,3 styrene-butadiene copolymer having 40% of styrene content, 30% present as a polystyrene block. It has BHT-free or phosphite-free non-staining antioxidant systems. It is a high purity polymer, essentially gel-free with a very clear color. Used in plastics, especially in high gloss HIPS by the “in situ” polymerization process. It is also used in vulcanized shoe soles giving high hardness, flexibility and abrasion resistance with good processability.
