DuPont™ Kalrez® 7075 perfluoroelastomer parts are a carbon black filled product that has enhanced physical performance properties including very low compression set and improved seal force retention. This product utilizes a proprietary cure technology with mechanical properties designed for improved sealing performance in both high temperature environments and temperature cycling situations. Kalrez® 7075, for the chemical processing industry, provides even greater sealing performance in dynamic applications where low friction is required. Kalrez® 7075 was specifically developed to be used as an o-ring or customer-sealing component in the chemical and hydrocarbon processing industries, with an improved thermal resistance that extends maximum service temperature to 327°C (620°F).
