ANNEX 1- Answer to question 6 from Europump 6:Missing uses - Analysis of alternatives and socio-economic analysis: Several PFAS uses have not been covered in detail in the Annex XV restriction report (see uses highlighted in blue and orange in Table A.1 of Annex A of the Annex XV restriction report).

ECGA position on the ECHA proposal to ban PFAS The current ECHA regulation proposal on PFAS is unjustified and disproportionate in relation to fluoropolymers.
