Fluororesin is well-known as a plastic that is not affected by acids or alkalis. I will explain the principle of why it does not dissolve in solvents such as acids and alkalis.
■Chemical Resistance of Fluororesin Fluororesin has high chemical resistance and does not dissolve, swell, or react with most acids, alkalis, and organic solvents. ■Reasons for High Chemical Resistance A major reason for the excellent chemical resistance of fluororesin is its stable molecular structure. Fluororesin is a high molecular polymer with a linear molecular structure formed by the bonding of carbon atoms and fluorine atoms. 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 tightly covered by fluorine atoms in a helical manner. Therefore, it remains inert when in contact with chemicals or solvents, and does not degrade or dissolve as a resin, which means it has excellent chemical resistance. ■Applications of Fluororesin's Chemical Resistance - Various gaskets - Packing materials - Piping and hoses - Storage tanks - Reaction vessels - Heat exchangers *For more details, please download the materials or refer to the link below.*

In 1968, we entered into a licensing agreement with DuPont in the United States. We began processing under the trademark "Teflon (TM) Coating" for industrial fluororesin coatings. As a certified processing manufacturer by DuPont (now Chemours), we offer coatings that maximize the properties of fluororesins tailored to our customers' needs. *“Teflon” is a trademark of Chemours.
