There are a number of problems that can be experienced in sanitary seal applications, many of which are related to thermal and chemical resistance challenges, compression set (permanent deformation), and high static friction (stiction). Such issues can lead to intrusion in the production line or dead space, which in turn elevates the risk of contamination or leakage.
The company says Kalrez LS390 has been purpose-designed to overcome these common challenges by providing high hardness properties (Shore A3 88), low stiction, temperature resistance up to 220°C and outstanding chemical resistance to process chemicals, WFI (water for injection), and SIP and/or CIP processes. For users, these properties facilitate greater MTBR (mean time between repair), delivering bottom-line cost savings.
Among early adopters of the parts is a major pharmaceutical plant in Japan. Here, Kalrez LS390 has successfully been deployed in an infusion-drop product operation that uses pure steam SIP. The manufacturer chose Kalrez® LS390 because of its improved chemical resistance and low stiction performance.
