General product information
Kalrez® 6375 is designed to give outstanding performance in the widest possible range of chemicals and temperatures. They are widely used in industries such as semiconductor manufacturing, chemical processing, oil and gas, automotive, food and beverage, and pharmaceutical production, where consistent sealing performance is critical. This product is an excellent choice for use in acids, bases, amines, steam, ethylene oxide, and many other aggressive chemicals. They are engineered for ultra-demanding environments, providing reliable sealing performance in both static and dynamic applications. Mixed streams, once a problem for many chemical processors, can now be handled by Kalrez® 6375.
The curing system also allows for a continuous upper service temperature of 275 °C. This high temperature stability translates to increased chemical resistance over all temperature ranges, especially if high temperature process excursions occur. This combination of chemical and thermal resistance provides advantages for chemical processors.
