Increasing Resistance to Thermal-Oxidative and Ozone Aging of Rubber Operating under Dynamic Loading Conditions

Abstract

Compositions of rubbers with increased resistance to thermal-oxidative and ozone aging and dynamic endurance have been developed based on mixtures of general and special purpose rubbers of varying degrees of saturation. Fatigue properties of rubbers under repeated stretching and alternating bending with rotation were studied. The tangent of the mechanical los angle and the time before the first cracks appear during are determined. Rubbers are designed for outdoor use under dynamic loading conditions.
