Abstract
A walkway pad composition comprises 100 parts by weight of an ethylene-propylene-diene terpolymer; from about 60 to 700 parts by weight of a filler selected from the group consisting of reinforcing and non-reinforcing materials and mixtures thereof, per 100 parts of the terpolymer; from about 40 to 175 parts by weight of a processing material and mixtures thereof, per 100 parts of the terpolymer; and from about 2 to 10 parts by weight of a cure package, per 100 parts of the EPDM
terpolymer, the composition being devoid of any additional polymeric components. The 100 percent EPDM walkway pad composition has better low temperature properties and superior weathering resistance, and heat aging resistance compared to other walkway pad compositions which may include other polymeric components such as natural rubber, synthetic polyisoprene, styrene-butadiene rubber (SBR), polybutadiene, and butyl (IR) rubber. Up to about 25 parts by weight of ethylene-propylene copolymers may be substituted for the EPDM terpolymers.
