Estimation of Wear Resistance of Tread Vulcanizates

Abstract

A simple procedure has been described to provide an estimate of the wear characteristics of a vulcanized polymer by means of a towing device. The present paper describes modifications that have been adopted to increase the efficiency of this procedure and reports the effect of various test conditions that have been explored by statistical methods. Estimates of the wear resistance of various types of rubber in suitable tread recipes are given together with an observed order of rating based upon their response to the severity of the imposed conditions.
