The value of fluorinated gas to polyurethane industry We would like to raise the below comments which call for the fluorinated gases that are used in our industry(1) to be fully exempted from the scope of the restriction proposal: In divergence from what the dossier submitters state, those substances are not classified as (very) persistent under REACH (they have atmospheric lifetime of days or months) and more importantly, they do not decompose in the environment into trifluoroacetic acid (TFA) in a meaningful fraction (see the EFCTC evidence (2)).

Per- and Polyfluoroalkyl Substances (PFAS): Incineration to Manage PFAS Waste Streams Background Per- and polyfluoroalkyl substances (PFAS) are a very large class of man-made chemicals that include PFOA, PFOS and GenX chemicals.

ll PRINSCO ENGINEERED WITH INTEGRITY _TECHNICAL NOTE POLYPROPYLENE CHEMICAL RESISTANCE Introduction Among many of the positive attributes of polypropylene, it is probably best known for its resistance to highly aggressive chemicals.

Attachment 2_Taking a long time for development of future alternative materials in printer & copier Need a huge time to phase-out PFAS used for printers EVEN IF the substitute material of PFAS is available in the future The substitute materials instead of PFAS to fulfil for many of necessary functions required in printing process is not available yet.

The advanced-packaging market is spurred by end applications.
