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.

Dear ECHA As to European Chemicals Agency (ECHA) Regulation Draft (published on Februar In the electric heaters manufactured by our company, namely, self-regulating heate The proposed regulations is just similar to the debate over whether to continue or s Nuclear power has outstanding performance.it is considered necessary for human b A series of regulation proposal by ECHA is just close to that is.
