The Long-Term Heat Resistance of Epichlorohydrin Hose and Tubing Compounds 750961

Due to rising under-the-hood temperatures and the trend in industry in general for longer life products, the long-term heat resistance of elastomeric materials is generating considerable interest. This paper reviews some of the compounding techniques necessary to develop the best long-term heat resistant epichlorohydrin compounds. The long-term (1000 hrs.) aging resistance of these materials will be compared to more conventional materials such as CR, NBR, CSM and EPDM compounds. Also blends such as Acrylate/Epichlorohydrin and Epichlorohydrin/Chlorobutyl will be reviewed as ways to obtain a balance of heat resistance and cost.
