Comment on Proposed Restriction of PFAS May 25, 2023 Japan Fluoropolymers Industry Association (JFIA) We, Japan Fluoropolymers Industry Association (JFIA), think that fluoropolymers should be distinguished from the proposed restriction of PFAS (Per- and polyfluoroalkyl substances), which collectively regulates more than 10,000 of organofluorine compounds (PFAS) on the grouping basis.
