Kalrez is chemical-proof synthetic rubber. It maintains the properties of rubber even at high temperatures.
The key strengths of Kalrez are that it has both the elasticity and seal characteristics of an elastomer and the chemical resistance and thermal stability of Teflon. Kalrez produces a small amount of gas in a vacuum and exhibits high resistance to a variety of chemicals such as ether, ketone, amine, oxidizing agents, and many other chemicals. Kalrez preserves the properties of rubber even when it is kept in contact with a corrosive fluid at high temperatures. Therefore, Kalrez is widely used in a number of industrial fields such as semiconductor manufacturing, chemical transportation, nuclear, aircraft, and energy.
- Kalrez is a brand name for perfluoroelastomer owned by DuPont, U.S.
