Royaltherm®

Royaltherm® is a silicone-modified EPDM.  It is ideally suited for high-temperature applications.  Compared to normal EPDM, Royaltherm® provides better heat and weather resistance.  Compared to silicone, it provides better tensile strength, flex fatigue resistance and other mechanical properties.  It exhibits good electrical properties in moist conditions and, unlike silicone, retains physical properties even in hermetically sealed environments.
