Airspring

Abstract

The present invention is directed to an airspring having an airsleeve comprising an elastomeric liner; a reinforcing layer overlaying the liner; and an elastomeric cover overlaying the reinforcing layer; the cover made from an a vulcanizable elastomeric composition comprising: 100 parts by weight of elastomer comprising from about 30 to about 50 parts by weight of natural rubber, from about 10 to about 30 parts by weight of polybutadiene, and from about 30 to about 50 parts by weight of ethylene propylene diene terpolymer (EPDM); from about 20 to about 60 parts by weight, per 100 parts by weight of elastomer, of silica; from about 1 to about 10 parts by weight, per 100 parts by weight of elastomer, of an organosilane polysulfide; from about 1 to 10 parts by weight, per 100 parts by weight of elastomer, of an organic peroxide; and from about 0.1 to about 40 parts by weight, per 100 parts by weight of elastomer, of a crosslinking coagent.
