Description: List of PFAS chemicals without explicit structures - polymers and other UVCB chemicals. The list was assembled by searching on the following substring list: Perfluoro, Polyfluoro, Fluoroethylene, Fluoropropylene, Fluorobutene, Fluoropolymer, "Ethene, 1,1,2,2-tetrafluoro" (the PTFE monomer unit), Chlorotrifluoroethylene, Difluoromethylene, Vinyl fluoride, Tetrafluoro, Pentafluoro, Hexafluoro, Heptafluoro, Octafluoro, Nonafluoro and Decafluoro and filtering out distinct chemical structures. This will retain Markush structure representations. This list remains under constant curation and expansion.
