DuPont Kalrez LS390 perfluoroelastomer parts are a grey product for use as sanitary seals in food handling, beverage, and pharmaceutical applications where FDA, USP <87> and <88> Class VI compliance are required.
In addition, DuPont Kalrez LS390 parts also meet Japan Pharmacopeia, edition 16*. Typical problems experienced in sanitary seal applications are usually related to thermal and chemical resistance challenges, compression set (permanent deformation) and high static friction (stiction).
These factors can cause intrusion in the production line or dead space, which increases the risk of contamination or leakage unless seals are continually tightened. DuPont Kalrez LS390 has been designed to address these issues by offering high hardness properties, low stiction, temperature resistance up to 220°C (428°F) and excellent chemical resistance (Tables 1 and 2) to process chemicals, WFI (water for injection), as well as SIP and/or CIP processes.
These properties, enable increased MTBR (Mean Time Between Repair). Because of its unique grey color, LS390 parts are easy to identify for proper material selection and application. For use in applications other than sanitary seals, please contact your DuPont™ Kalrez® perfluoroelastomer parts representative.
