Solprene® 4318

Solprene 4318 is a linear block copolymer of styrene and butadiene, having 32% of styrene content, most of it forming a polystyrene block, which gives the polymer a thermoplastic behavior.It has a non-staining antioxidant system; FDA approved for use in food contact applications and is essentially gel free with a clear color.Solprene 4318 is used as compounding ingredient for adhesives. The product is an excellent modifier for asphalt applications including self-adhesive roofing membrane and sealant. Also is used in thermoplastic injected shoe soles formulations.
