Rubber V & U Seal

Vulcanizates based on Viton™ provide an exceptional balance of physical property characteristics, including the following features: Resistance to Temperature Extremes Heat—Compared to most other elastomers, Viton™ is better able to withstand high temperature, while simultaneously retaining its good mechanical properties. Oil and chemical resistance are also essentially unaffected by elevated temperatures. Compounds of Viton™ remain substantially elastic indefinitely when exposed to laboratory air oven aging up to 204 °C (399 °F) or to intermittent exposures up to 316 °C (601 °F). High temperature service limits are generally considered to be: – 3,000 hr at 232 °C (450 °F) – 1,000 hr at 260 °C (500 °F) – 240 hr at 288 °C (550 °F) – 48 hr at 316 °C (601 °F) Cold—Viton™ low temperature performance is dependent on type, with serviceability as low as –31 °C (–24 °F) in dynamic seals and –45 °C (–49 °F) in static seals using Viton™ GLT-S.
