Development of Wear-Resistant Elastomers for Track Pads

Abstract

Correlation between service test wear ratings and laboratory test data obtained at room temperature for tear strength, resistance to crack growth, and abrasion resistance, as previously reported by the Research Directorate of this Command, has been confirmed in the most recent service test conducted at ATAC and Yuma. Of even more importance was the finding that the results of tear tests and crack growth tests conducted at 250 F correlated with service test wear ratings. Track pads prepared from HYTRANS 1227-289-1, Philprene 1609/cis-4 1350, Stereon 750, and Ameripol 1834/Ameripol CB1352 have exhibited up to 56 per cent improvement in tread wear resistance when compared with commercial SBR control pads. On the basis of these results, pads prepared from these experimental compounds should have an average service life of 3000 to 3500 miles. This is an important step toward the ultimate goal of a 5000 mile track pad.
