THE ACCELERATED AGEING OF SOME COMMERCIAL POLYURETHANE RUBBERS

Abstract

Nineteen commercial polyester urethane rubbers, and one commercial polyether urethane rubber were subjected to accelerated laboratory ageing for periods of up to two years under hot/dry, hot/wet, and hot/humid conditions, and for up to two years immersed in Standard Test Fluid. The results obtained on the polyether urethane were similar to those obtained in previous trials. The best polyester urethane (a development material) had a life under hydrolytic conditions of five to eight times that normally expected from commercially available polyester urethanes.
