The Performance of NHBR and Low Temperature HNBR in Various Automotive Parts 942428

A variety of current and developmental automotive fluids were evaluated to determine their effects on Hydrogenated Nitrile Butadiene Rubber (HNBR), and low temperature HNBR (LT-HNBR) compounds to assist in predicting their performance in automotive sealing applications. This study provides the materials and design engineer with a concise overview of elastomer performance in these fluids and demonstrates the unique attributes of HNBR elastomers. This new family of polymers provides the benchmark for enhanced performance in automotive seals by extending the functional operating range and sealing capabilities while still offering a price/performance advantage over high priced specialty elastomers.
