Fluoro rubber o-rings is a kind of commonly used material. What features does Fluoro rubber o-rings have?

Fluoro rubber o-rings is made of vinyl fluoride, hexafluoropropylene, and a variety of formulations. It has good flame retardancy, airtightness, high temperature resistance, oil resistance, solvent resistance, flame resistance, chemical resistance, and climate resistance. It is usually used in the automobile industry, chemical process, aerospace, and many industries.

The operating temperature of fluoro rubber O-ring can reach 250 ℃ and 300 ° C for a short time. It is famous for its high temperature resistance and chemical resistance. In addition, it also has good anti-aging and anti-oxidation, very low gas permeability (especially for high-altitude installations), but fluorine rubber is also divided into many varieties, and there is a little difference between varieties.

Fluoro rubber o-rings fuel oil, hydraulic oil, organic solvent, concentrated acid, strong bismuth agent, and other functions have stability, but there are differences among different varieties. For example, in the medium of fuel oil, hydraulic cylinder oil, diester, silicate ester lubricating oil, and boiling water, the performance of type 23 fluoro rubber is worse than that of type 26 fluoro rubber in the environment. For example, peroxide vulcanization system products have better water resistance than ammonia and phenol vulcanization system products.

The disadvantages of Fluoro rubber o-rings are poor processability, high cost, poor cold resistance, low elasticity, and permeability.
