Abstract
The present invention is directed generally to track segments for track vehicles and, more specifically, to a track segment having an ethylene propylene diene monomer (EP(D)M) rubber based backer, and a method of making. In one embodiment, the track segment includes an EP(D)M rubber based backer including a rubber compound having 100 phr EP(D)M rubber wherein the diene component is optionally present, a peroxide curing agent, and one or more acrylic and/or methacrylic coagents. The track segment further includes a track pad and a track body. The track pad and backer cooperate with the track body to define the track segment for use in a track for a track vehicle. The EP(D)M rubber based compound provides a desirable balance of low heat build-up under heavy dynamic cyclic compression conditions, and also has a desirable load carrying capability, high heat resistance, and good cut/tear strength in hot climates.
