Unlike with PTFE, the alkoxy substituents allow the polymer to be melt-processed. On a molecular level, PFA polymers have a smaller chain length and higher chain entanglement than other fluoropolymers. They also contain an oxygen atom at the branches. This results in materials that are more translucent and … Ver mais Perfluoroalkoxy alkanes (PFA) are fluoropolymers. They are copolymers of tetrafluoroethylene (C2F4) and perfluoroethers (C2F3OR , where R is a perfluorinated group such as trifluoromethyl (CF3)). The … Ver mais PFA is commonly used as a material for piping and as fittings for aggressive chemicals, as well as the corrosion-resistant lining of vessels in the chemical-processing industry. … Ver mais The monomers of such Perfluoroalkoxy alkane polymers, in common with other per- and polyfluoroalkyl substances, are widespread in the environment due to human production … Ver mais Common trademarks include Teflon-PFA, Hostaflon-PFA and Chemfluor.
