Development of Rubber Pads for Tracked Vehicles

Abstract

Improvement in the wear resistance of rubber track pads was sought through compounding studies and evaluation of rubber-to-metal bonding agents. Correlation was sought between laboratory tests on the rubber component of track pads and service tests on the entire pad. Track pads fabricated from millable polyester urethanes provided improved service over that of commerical control pads. Small amounts of calcium oxide in millable polyester urethane vulcanizated eliminates the internal porosity which leads to early failure of track pads in high speed service tests but has an adverse effect on hydrolytic stability and wear resistance. Initial correlation efforts using the DeMattia and Firestone Flexometer tests are sufficiently interesting to warrant further examination. A satisfactory rubber-to-metal bonding system for millable polyester urethanes has been found.
