This document explains the principle that Teflon/fluororesin does not dissolve in solvents such as acids and alkalis.
■Chemical Resistance of Teflon / Fluororesin Teflon resin has high chemical resistance and does not dissolve, swell, or react with most acids, alkalis, and organic solvents. ■Reasons for the Excellent Chemical Resistance of Teflon / Fluororesin A major reason for the excellent chemical resistance of Teflon resin and fluororesin is its stable molecular structure. Teflon resin and fluororesin have a molecular structure where carbon atoms and fluorine atoms are connected in a linear chain. The bond energy of the carbon-fluorine (C-F) bond is very strong among chemical bonds, and furthermore, the C-C bond between carbon atoms is completely covered by fluorine atoms in a helical manner. Therefore, even when in contact with chemicals or solvents, they remain inert and do not degrade or dissolve as a resin, which means they have excellent chemical resistance. ■Products Utilizing the Chemical Resistance of Teflon / Fluororesin The chemical resistance of Teflon resin and fluororesin is used in various products in the chemical industry, semiconductor field, and medical and pharmaceutical sectors, such as: - Various gaskets - Packing materials - Pipes and hoses - Storage tanks - Reaction vessels - Heat exchangers *For more details, please download the materials or refer to the link below.*

Applications/Examples of results
At Yoshida SKT, we have been providing fluoropolymer coatings that utilize the excellent properties of fluoropolymer resins since 1963. 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 fluoropolymer coatings. As a certified processing manufacturer by DuPont (now Chemours), we offer coatings that maximize the properties of fluoropolymer resins tailored to our customers' needs. * "Teflon" is a trademark of Chemours. Please feel free to contact us regarding our fluoropolymer coatings that are highly resistant to chemicals.
