Calprene® 7318

Calprene 7318 is a linear block copolymer of styrene and butadiene, having 32% 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 very clear color.Calprene 7318 is BHT* and nonylphenol free SBS, according to existent food contact regulations (Europe and America)Calprene 7318 is specially designed for technical compounds and adhesives.It is presented as free flowing porous crumb making easy its handling and dissolution.*(BHT content in pure polymer less than 30ppm).
