Fluororesin, famous for being resistant to acids and alkalis. I will explain the principle of why it does not dissolve in solvents such as acids and alkalis.
■Is the chemical resistance of fluoropolymer high? Fluoropolymers have high chemical resistance and do not dissolve, swell, or react with most acids, alkalis, and organic solvents. ■Reasons for the high chemical resistance of fluoropolymers A major reason for the excellent chemical resistance of fluoropolymers is their stable molecular structure. Fluoropolymers are high molecular weight polymers with carbon atoms and fluorine atoms bonded in a linear chain structure. The bond energy between carbon and fluorine atoms (C-F) is very strong among chemical bonds, and furthermore, the C-C bond sections between carbon atoms are completely covered by fluorine atoms in a helical manner. Therefore, they remain inert when in contact with chemicals or solvents, and do not degrade or dissolve as a resin, which means they have excellent chemical resistance. ■Uses of fluoropolymers The chemical resistance of fluoropolymers is utilized in the chemical industry, semiconductor industry, and medical and pharmaceutical fields in products such as: - Various gaskets - Seals - Piping and hoses - Storage tanks - Reaction vessels - Heat exchangers *For more details, please download the materials or refer to the link below.
