ACM elastomers have undergone continuous development to improve long-term performance, resulting in heat and oil resistant gaskets and seals that are widely used in automotive applications. Several years ago, Zeon Corporation introduced a new family of heat and oil resistant ACM polymers known throughout the industry as AR12 and AR14. The superiority of these new elastomers over traditional ACM elastomers has been successfully demonstrated in many under-hood applications, including oil pan gaskets, rocker cover gaskets, and seals. With the continued loss of open space in the engine bay, temperatures have risen to well over 150 deg C. However the low-temperature performance requirements have not changed from minus 40 deg C functionality. Expanded service temperature range, on both the low and high ends, has become the new target for elastomers used in automotive applications. Zeon Chemicals L.P. has recently introduced HyTemp AR214, with a service temperature range from -40 deg C to +165 deg C, aimed at this market segment. The objective of this paper is to demonstrate the compounding versatility, physical properties, and heat resistance of this new ACM elastomer.
