A Study of Mechanical, Oil Resistance, and Low Temperature Resistance of NBR Vulcanizates

Abstract:

In this study, mechanical properties, oil resistance of Nitrile Butadiene Rubber (NBR) as material of an automotive were investigated at low temperature conditions. In order to find the optimum formulation used various grades of NBR with different contents of Acrylonitrile (ACN) such as NT1846F, DN407, B7150, B6240 and N215SL. The mechanical properties, oil and low temperature resistance of NBR were measured using moving die rheometer, durometer, universal testing machine, differential scanning calorimetry, and Gehman tester. The hardness was increased with an increased ACN contents. The low temperature resistance, and degree of swelling were increased that decreased ACN contents have lower T_g, lower value of Gehaman test.
