Poly(difluoromethylene), α-fluoro-ω-[2-[(1-oxooctadecyl)oxy]ethyl]-

Made for industrial coatings and treatments in textiles, paper/packaging, electronics, and other water‑/oil‑repellent uses [1][2].

Mainly at work during manufacturing or high‑heat processing (dust/fumes). The public may encounter treated products, indoor dust, or PFAS in water/air near facilities [1][2].

PFAS can build up in people; some (like PFOA) are linked to immune, liver, cholesterol, and cancer risks. Overheated fluoropolymers can emit hydrogen fluoride and ultrafine particles that cause “polymer fume fever” [1][3][4][5].

Fluoropolymer production/coating workers; people using high heat on fluoropolymer‑coated items without good ventilation; pet birds are very sensitive to fumes [3].

Use moderate heat and ventilation with nonstick/fluoropolymer‑coated items; avoid damaged cookware; choose PFAS‑free products when feasible; at work, use local exhaust, PPE, and follow safety data sheets and hygiene practices [1][2][3][5].
