DuPont™ Kalrez® 6230

In food, dairy, and pharmaceutical manufacturing, hygiene, purity, and material durability are critical factors in ensuring product quality and process stability. One of the most demanding applications in the dairy industry is the homogenizer, where O-rings and sealing components must withstand high temperatures, extreme pressures, and rapid rotational speeds. If seals fail to perform, milk fat can agglomerate or coagulate during storage, compromising product quality.

To meet these rigorous requirements, DuPont™ Kalrez® 6230 was developed — a high-performance perfluoroelastomer (FFKM) sealing solution designed specifically for food, beverage, and pharmaceutical processing environments.

Key Features of Kalrez® 6230

✅ FDA and USP Class VI Compliant
Kalrez® 6230 complies with the U.S. FDA Food Contact Notification (FCN) #101 and USP Class VI standards, authorizing repeated use in food contact applications.
According to FCN #101, Kalrez® parts demonstrate extremely low extractables (≤0.2 mg/in²), minimizing the risk of contamination and ensuring superior product safety.

✅ Exceptional Resistance to Heat and Chemicals
Performs reliably in high-temperature environments with excellent resistance to acids, bases, solvents, and steam.
Maintains elasticity and sealing integrity through harsh CIP/SIP (Clean-In-Place/Sterilize-In-Place) cycles commonly used in food and pharmaceutical facilities.

✅ Stable Performance in Rotating Equipment
Widely used in O-ring seals for food homogenizers, Kalrez® 6230 ensures long-lasting performance with no leakage, deformation, or loss of mechanical strength — even under continuous high-pressure and high-speed conditions.

✅ High Purity – No Carbon Black or Metal Fillers
Manufactured without carbon black or metallic fillers, Kalrez® 6230 minimizes contamination risks, fully meeting hygienic design requirements for applications in dairy, beverages, pharmaceuticals, and cosmetics.

Typical Applications

• O-rings and seals in food homogenizers

• CIP/SIP systems, mixers, and packaging equipment
