Perfluoroether rubber compound
Perfluoroether rubber is the most resistant material to high temperature and chemical solvents among all elastomer sealing materials. It is resistant to chemicals and corrosive media such as strong acids, strong alkalis, ketones, ethers, alcohols, esters, aldehydes, hydrocarbons, nitrogen-containing compounds and amino compounds, which are not resistant to ordinary rubber and fluororubber. Perfluoroether can be widely used in petrochemical industry, chemical industry, pharmaceutical industry, solvent equipment, aerospace equipment, nuclear energy industry according to various working environments and temperatures, especially in the extremely harsh environment of photolithography, chemical etching and chemical cleaning in the production process of semiconductors, which requires extremely high thermal stability and chemical resistance, and perfluoroether can play a great role.
