DuPont™ Kalrez® 6221

DuPontTM 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. DuPontTM 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. For white custom parts, please refer to Kalrez® LS205 parts.
