Perfluoroalkoxy alkanes (PFA) are fluoropolymers. They are copolymers of tetrafluoroethylene (C 2 F 4) and perfluoroethers (C 2 F 3 OR f, where R f is a perfluorinated group such as trifluoromethyl (CF 3)). The properties of these polymers are similar to those of polytetrafluoroethylene (PTFE). Compared to PTFE, PFA has better anti-stick ...
Although there is a separate PFA Young Player of the Year award, young players remain eligible to win the senior award, and on three occasions the same player has won both awards for a season, Andy Gray in 1976–77, Ronaldo in 2006–07 and Bale in 2012–13.
Skeletal structure of PFOS, an effective, persistent and bioaccumulative fluorosurfactant A physical sample of PFOA, appearing as a white solid as seen here in a relatively pure form. It is commonly referred to as the main harmful PFAS chemical and PFOA is responsible for many of the negative health effects commonly associated with PFAS.
The Professional Fraternity Association (PFA) is an American association of national, collegiate, professional fraternities and sororities that was formed in 1978.

Short-chained POM (chain length between 8 and 100 repeating units) is also better known as paraformaldehyde (PFA). As with many other synthetic polymers , polyoxymethylenes are produced by different chemical firms with slightly different formulas and sold as Delrin, Kocetal, Ultraform, Celcon, Ramtal, Duracon, Kepital, Polypenco, Tenac and ...
Paraformaldehyde (PFA) is the smallest polyoxymethylene, the polymerization product of formaldehyde with a typical degree of polymerization of 8–100 units. Paraformaldehyde commonly has a slight odor of formaldehyde due to decomposition. Paraformaldehyde is a poly-acetal.
