This was an EPA lead inspection. 8) Facility Description The Arkema Group produces specialty materials, including acrylic monomers, adhesives, emulsion systems, fluorochemicals, fluoropolymers, functional additives, hydrogen peroxide, specialty polyamides and thiochemicals, for use in products such as vehicles, cosmetics, aeronautics, packaging, electrics, and sporting goods.

Trying to replace them in their many applications would lead to substitution with alternatives (when available) that do not provide the same advanced performance and safety as fluoropolymers.
