Viton O-ring seals high temperature performance with high chemical stability, high temperature resistance, aging resistance, resistance to media at present is the best performance of all kind of elastomers. High temperature properties of fluorine rubber and silicone rubber, as can be said is the best elastomer (hereinafter referred to as fluoro rubber). Viton long-term use at 250 ℃. High temperature O-ring has excellent resistance to weather aging, ozone resistance. According to reports, DuPont developed VitonA years after natural storage performance remains satisfactory, 0.01% of the air after 45 days there is no obvious effect of cracking in the ozone concentration. 23 fluorine rubber weather aging, ozone resistance is also excellent. O-ring having an excellent high temperature vacuum performance, vulcanized rubber vacuum outgassing rate was 37 × 10-6 torr liter / sec. Cm 2, has been successfully applied in a vacuum of 10-9 Torr. High temperature O-ring has excellent mechanical properties. 26 fluorine rubber General Combining strong between 10 ~ 20MPa, elongation at break between 150 to 350%, tear strength between 3 ~ 4KN / m. 23 fluorine rubber strength between 15.0 ~ 25MPa, elongation of 200% to 600%, tear strength between 2 ~ 7MPa. In general, the fluorine rubber compression in large permanent deformation at high temperatures, but if the conditions are the same, such as compression from the same time 150 ℃ under permanent deformation, the small and neoprene than 26 fluorine rubber should be large, 26 fluorine rubber compression 200 ℃ × 24 hours of deformation equivalent butadiene rubber in 150 ℃ × 24 hours compression. Electrical properties are better fluorine rubber, low moisture absorption than other elastomers, may be used as an electrical insulating material preferably can be used under a low pressure at low frequencies. Viton on the solubility of gases is relatively large, but the diffusion rate is relatively small, so the overall performance out of permeability is also small. Fluoro rubber at 30 ℃ for oxygen, nitrogen, helium, carbon dioxide gas permeability and butyl rubber, butyl rubber rather, than neoprene, natural rubber is better.
