Material Notes:

Calprene 375 is a Butadiene/Styrene Copolymer, polymerized in solution. It has a random structure with a typical vinyl content of 30%, and is extended with 37.5 phr of naphthenic oil. C-375 is used as ingredient in compounds for battery cases, tires, cables, vulcanized shoe soles and industrial rubber goods. It can replace SBR 1707, 1708, 1778 types. The bales are wrapped in low melting point polyethylene film.Applications: TiresFootwearMechanical rubber goodsCompound Test Recipe: ISO-2322 (A)Information provided by Dynasol.
