HNBR, A FUNCTIONAL DESCRIPTION OF PERFORMANCE

In this article the relationship between compounding and inherent prop erties of HNBR grades related to low temperature performance and high temperature ageing in air and power steering fluids will be addressed. Ageing is analysed quantitatively as a function of time and temperatu re with an empirical method, Results are converted into maximum contin uous operating temperatures. Data for HNBR grades and for HNBR in a po wer steering seal application are analysed.
