Kalrez® Industry Applications

Superior performance in the harshest processing environments

For over 25 years, Kalrez® perfluoroelastomer parts have been providing the ultimate in sealing performance in the harshest processing environments. Some of the industries and applications in which Kalrez® parts provide superior performance include:

Chemical Processing – In pumps, valves, reactors, flange joints and other equipment, Kalrez® parts—whether O-rings, custom shapes or valve stem packing systems—are proving their value year in and year out as the best choice for long-term, reliable service.

Semiconductor – The success of Kalrez® has been field-proven in the manufacture of semiconductors, where processing steps can involve extremes of both thermal and chemical exposure.

Life Sciences – Life Sciences applications such as pharmaceutical, medical packaging and the food and beverage industries require the highest standards of safety, temperature and chemical resistance in production. To achieve this they need high performance seals that can ensure efficiency and cleanliness.

Aerospace – High-performance Kalrez® parts provide reliable and long-lasting sealing performance for the military, commercial and general aviation industry. They are used as oil seals in gas turbine engines and air delivery systems.

Oil and Gas – Kalrez® parts stand up to severe down-hole conditions—from high pressures and temperatures, to aggressive sour gas and corrosive fluids.

Photovoltaic – Kalrez® seals for photovoltaic cell manufacturing processes retain their elastomeric properties at temperatures as high as 325°C, & resist over 1800 chemicals including alkalis, acids, solvents, O2 and fluorine-based plasma.
