Comparison of NBR with Other Oil Resistant Rubbers for Automotive Applications

Notable improvements have been made recently in the high temperature performance of NBR vulcanizates and in the test methods used to predict the performance of these and other oil resistant elastomers. The good overall balance of properties achievable with current NBRs enables them to play a major role alongside more expensive oil resistant elastomers. More specifically the high temperature performance now available in NBR-based parts is already being exploited extensively and further applications are under test. High temperature performance using non-interfering stabilizers in NBR is comparable to that of “bound antioxidant” NBR in many practical compounds.
