ABSTRACT:
A chlorinated rubber composition which is resistant to various fluids such as transmission fluids comprises a blend of a chlorinated polyethylene elastomer, an ethylene acrylic elastomer and/or polyacrylic rubbers, and optionally a chlorosulfonated polyethylene. The rubber composition has many uses such as a tube and generally contains various additives such as fillers, plasticizers, vulcanizing agents, and the like.A heat resistant rubber composition comprises a blend of a chlorinated polyethylene elastomer, an ethylene-acrylic elastomer and/or polyacrylic rubbers, an ethylene-octene copolymer, and an ethylene-propylene-diene terpolymer, and the same can be used as a cover or jacket as on the above chlorinated rubber tube.
