Solprene® 1205

About
Solprene1205 is a linear random-block styrene/butadiene copolymer having 25% of styrene content, 17.5% present as a polystyrene block. 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. Solprene 1205 is an excellent modifier for asphalt, for formulation of caulks and sealants; it is also an excellent processing aid for most polymers, giving good low temperature resistance. Used in extruded goods, soles, and heels. It can also be used as modifier for thermoplastic resins and in adhesive formulations. It is available in bales wrapped in low melting point polyethylene.&&
