Chemours calls for focused PFAS research, controls
News
24 Oct 2019 | Bloomberg Environment
Chemours, facing hundreds of millions in liability, believes that the regulatory focus should be on the non-polymer category of PFAS. Efforts also should include a look at side-chain fluorinated polymers because “these compounds do have the potential to degrade under certain conditions to form non-polymer PFAS." Chemours has also committed to making its authentic reference standards publicly available and called upon the rest of the fluoropolymer industry to do the same.
