DuPont™ Kalrez® 6221

DuPont Kalrez 6221 perfluoroelastomer parts are a white product that provide superior chemical resistance and low contamination from extractables in pharmaceutical and food handling applications where FDA compliance is required. DuPont Kalrez 6221 parts are especially suited for Water for Injection (WFI) systems, Steam-in-Place (SIP) cleaning and other critical systems. Kalrez° 6221 parts are thermally stable up to 260°C (500°F), permitting them to be used in Stage II Sterilization processes, where other elastomers lose their sealing ability. Kalrez® 6221 is available as O-rings.
