Solprene® 1217

Solprene® 1217 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. Is BHT/TNPP free.

FDA approved for use in food contact applications. Is essentially gel free with a clear color.

Solprene 1217 is used as compounding ingredient for adhesives, as modifier for thermoplastic resins. It is an excellent modifier for asphalt, formulations of caulks and sealants;  is also an excellent processing aid for most polymers, giving a good resistance to low temperature. Used in extruded goods, soles, and heels.

 Available in bales wrapped in low melting point polyethylene. In case of polymer modification by chemical reaction it can be wrapped in styrene-butadiene film.
