Viton was first introduced in the 1950's for the aerospace industry to fulfill the need for a high performance sealing elastomer. Since then, viton has maintained a reputation for its outstanding performance in extreme heat and extremely corrosive environments.
Viton offers an exceptionally high resistance to compression set, even at high temperatures. It is known to have an exceptionally good resistance to oxidation, sun and weather, along with an excellent resistance to fungus and mold.
Viton is capable of withstanding high temperatures while retaining its good mechanical properties, and is better at it than most other elastomers. The oil and chemical resistance are virtually unaffected by elevated temperatures, and the compounds remain relatively elastic indefinitely up to temperatures of 400° F (204° C)
The high temperature limits are as follows:
Viton is usually serviceable in applications down to between 0° F and -10° F (-18° C to -23° C). It has also been proven to be satisfactory for static seals under conditions approaching absolute zero temperatures.
