Effect of Severity of Service on the Relative Abrasion Resistance of Natural Rubber, GR-S-10, and GR-S-100

Abstract

Abstract The data in this report show that the rate of wear is affected very greatly by the severity of the test. Both laboratory and actual road wear performance data show that synthetic rubber and natural rubber are fairly similar in rate of wear under mild conditions of testing, but in severe service the synthetic polymers are vastly superior to natural rubber. It therefore becomes evident that, in order to correlate laboratory data with road test results, the severity of service must be known, and a laboratory test conducted under one set of conditions would not necessarily be expected to correlate with all road test results.
