Explanation
A type of elastomer obtained by H-membered copolymerization of perfluoromethylethyl ether, tetraethylene, and perfluoroallyl ether It also has thermal stability and chemical stability of elasticity and polytetrafluoroethylene; It is still plastic below the embrittlement temperature, hard but not brittle, and can be bent except for swelling in fluorinated solvents. Stable for all chemicals. fluoroether rubber is made by emulsion polymerization of full gas (methyl vinyl) ether, tetrafluoroethylene and a small amount of perfluoroethylene ether. It is vulcanization by amphiphilic substitution of diamine or 2,2-bis (4-phenylhydroxypropane) with fluorine on perfluoroethylene ring. Its processing performance is poor, and it is used in occasions where fluoro rubber is not competent and the conditions are harsh. Make seals resistant to various media, such as rocket fuel, hydrazine, oxidizer, nitrogen tetroxide, fuming nitric acid, etc., for aerospace, aviation, chemical, petroleum, nuclear and other industrial sectors.
