The Premium Elastomer for Demanding Applications

Do you need an elastomer o-ring or sealing solution built to handle even the most extreme conditions? Meet Chemraz®, our highest-performing elastomer and the ultimate FFKM material. With temperature ratings up to 325°C (617°F), nearly universal chemical compatibility, and the broadest chemical resistance of any elastomeric material, Chemraz® is the prime choice for the most challenging industrial, aerospace and defense, semiconductor, energy, and pharmaceutical applications.

High Pressure and Temperatures are No Match

For rubberized parts that can perform in environments hotter than 200°C (392°F), Fusion® FKM is your best bet. FKM is a fluorinated, carbon-based synthetic rubber built to withstand extreme temperatures, high pressures, corrosive chemicals, and volatile fluids (including several fuels). Fusion® materials are typically used to manufacture O-rings, seals, and gaskets for demanding applications in extreme environments.

A Durable, Versatile FEPM Elastomer

If you need an elastomer solution that can withstand a wide range of volatile and corrosive chemicals, Fluoraz® FEPM is for you. Designed for demanding applications, these elastomers provide strong chemical resistance against acids and bases like methanol, amines, ammonia, urea, and hydrochloric acid. They can handle heat and steam at temperatures up to 232°C (450°F), and offer several advantages over a standard FKM solution.

Elastomer Solutions for Extreme Temperatures and Chemicals

If you need rubberized parts with aggressive chemical and temperature resistance, Xyfluor® is made for you. This highly fluorinated elastomer easily handles amines, ketones, and hydrofluoric acid for static applications in temperatures ranging from -76°F (-60°C) to 450°F (232°C). Xyfluor® is ideal for use in demanding high-volume applications such as mechanical seals and gaskets in a range of metering pumps, valves, and other high-performance equipment.
