Abstract
A hose made from a composition including one or more of EPR, EPDM, a silane-grafted polyolefin and a silicone-modified polyolefin; and 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 silicone-modified polyolefin; and (B) at least one of an ultra high molecular weight polyethylene powder, a polyamide powder, and fibers.
Claims16
A hose comprising
- a tube;
- a reinforcement layer circumferentially surrounding the tube;
- and
- a cover layer circumferentially surrounding the reinforcement layer,
- wherein the cover layer is formed from a composition comprising:
- (A) a silane-grafted polyolefin;
- and
- (B) at least one of an ultra high molecular weight polyethylene powder, a polyamide powder, and fibers.
A hose comprising
- a tube;
- a reinforcement layer circumferentially surrounding the tube;
- and
- a cover layer circumferentially surrounding the reinforcement layer,
- wherein the cover layer is formed from a composition comprising:
- (A) at least one of EPR and EPDM,
- (B) a silane-grafted polyolefin;
- and
- (C) an ultra high molecular weight polyethylene powder.
An automotive heating and cooling system or an automotive transmission system comprising:
- a hose;
- wherein the hose comprises
- a tube;
- a reinforcement layer circumferentially surrounding the tube;
- and
- an outermost layer;
- wherein the outermost layer is a cover layer circumferentially surrounding the reinforcement layer;
- and
- wherein the outermost layer is formed from a composition that comprises
- (A) a silane-grafted polyolefin and
- (B) at least one of treated short aramid fibers, a polyamide powder having an average particle size in the range of from about 10 μm to about 100 μm, and an ultra high molecular weight polyethylene powder having an average particle size in the range of from about 10 μm to about 100 μm;
- or wherein the outermost layer is formed from a composition that comprises
- (C) at least one of EPR and EDPM,
- (D) a silane-grafted ethylene-propylene-diene terpolymer polyolefin and
- (E) an ultra high molecular weight polyethylene powder having an average particle size in the range of from about 10 μm to about 100 μm.
