PFOA's are employed in 100's of industrial uses, including within the fields of aerospace, automotive, building and construction, chemical processing, electronics, semiconductors and textile industries. Interestingly, though fluoropolymers are made using PFOA, the finished products are not expected to contain PFOA.
