Abstract
A hose made from a composition including one or more of EPR, EPDM, a silane-grafted polyolefin and a silicone-modified polyolefin; an one or more of fibers, polyamide powder, and ultra high molecular weight polyethylene powder. A hose comprising an outermost layer formed from a composition comprising: (A) at least one of EPR, EPDM, a silane-grafted polyolefin and a siliconemodified polyolefin; and (B) at least one of an ultra high molecular weight polyethylene powder, a polyamide powder, and fibers.
Claims23
A hose comprising an outermost layer formed from a composition comprising:
- (A) at least one of a silane-grafted ethylene-propylene-diene terpolymer polyolefin and a silicone-modified ethylene-propylene-diene terpolymer;
- and
- (B) an ultra high molecular weight polyethylene powder.
An automotive heating and cooling system comprising:
