ABSTRACT OF THE DISCLOSURE A highly improved elastomeric-composition, process, and articles made thereof, wherein the novel composition is characterized by greatly increased wear longevity, thermomechanical stability, highly improved tear and tensile strength at high temperature useage, in addition to high resistance to burning in open flame, as well as high resistance to cutting, chipping, cracking and crack propagation particularly in product use for tank track pads and other related track system elastomeric component products; wherein the improved composition is a unique combination of its respective polymer, filler, curing and antidegradant systems, in which the polymer system either consists of about 100 parts by weight of highly saturated nitrile polymer or of various novel blends of the highly saturated nitrile usually in majority amounts together with minority amounts of carboxylated nitrile, with or without additional minority or near equal parts of nitrile rubber; and wherein the curing system may include various blends of from between about 1.5 to about 30 parts by weight of a metallic oxide, along with from between about 25 to about 50 parts by weight of a metallic methyl-methacrylate resin, together with from about 0.25 to about 3 parts by weight of a curative compound; which composition is further well suited for manufacture of various abutment and motion stop or limit members subjectable to repetitive engagement by moving mechanisms, and for various at least semi-flexible baffle or skirt-like members useable with various air cushion type vehicles or the like.
