Advanced Performance is Critical
In pharmaceutical and food processing sealing applications where cleanliness is critical, PTFE has been the material of choice, until now. Kalrez® perfluoroelastomer parts offer the same level of cleanliness and universal chemical resistance, but unlike PTFE they have true elastomeric properties and sealing capabilities.
FDA-compliant Kalrez® 6221 and 6230 parts provide low contamination from extractables. They are well-suited for contact with highly pure and aggressive water (WFI) systems and exhibit very low swell and loss of mechanical properties after repeated steam cycling.
DuPont™ Performance Polymer is the only supplier that manufactures both the Kalrez® polymer and the finished parts made of Kalrez®. We provide full traceability—an attribute that is highly desirable for your critical applications. We offer parts in standard shapes (such as O-rings and our new sanitary seal) and can also produce custom shapes, cord and sheeting.
