Perfluoroalkoxy copolymers

Somewhat between PTFE and PFA materials is the product Hostaflon TFM, which is a copolymer of TFE and a small amount of the perfluoro(propyl vinyl ether). It has improved impact strength and weldability and has been promoted as a suitable material for forming into bottles. Yet another TFE-perfluoroalkoxy copolymer was introduced by Du Pont in 1979 as Teflon EPE. This material had a somewhat lower melting point (295 °C) than the more common PFA fluoropolymers but it is no longer marketed. [Pg.378]

Screening tests were conducted on potential construction materials. The candidate materials evaluated included the following polytetrafluoroethylene (PTFE, TFE), fluorinated ethylene-propylene copolymer (FEP), perfluoroalkoxy-alkanes (PFA), ethylene-tetrafluoroethylene copolymer (ETFE), ethylene-chlorotrifluoroethylene copolymer (E-CTFE), poly vinylidene fluoride (PVDF), polypropylene (PP), and polyvinyl chloride (PVC). These materials were chosen based on cost, availability, and information from manufacturers on compatibility with acid solutions. [Pg.317]

Modified PTFE — Copolymer of TFE and a small amount (less than 1%) of other perfluorinated monomer (e.g., perfluoroalkoxy monomer) exhibiting considerably improved physical properties, moldability, and much lower microporosity. [Pg.170]

Perfluoroalkoxy resin (PFA) is a copolymer of TFE and perflnoropropy-1 vinyl ether (PPVE) in a mole ratio of approximately 100 1. Even snch a small amonnt of comonomer is snflicient to prodnce a copolymer with a greatly rednced crystallinity. The relatively long side chains also markedly rednce the cold flow. Methylflnoroalkoxy resin (MFA), a copolymer of TFE and perfln-oromethylvinyl ether (PMVE), has similar properties with a somewhat lower melting point. [Pg.31]

The need for highly fluorinated thermoplastic polymers that, unlike PTFE, could be fabricated by conventional melt-processing methods led to the development of a group of resins that are copolymers of tetrafluoroethylene (TFE) with other perfluo-rinated monomers. Commercially, the copolymer of TFE and hexafluoropropylene (HEP) is commonly known as fluorinated ethylene propylene (FEP). Copolymerization of TEE with perfluoropropylvinyl ether (PPVE) leads to perfluoroalkoxy (PEA) resins, and copolymerization of TFE with perfluoromethylvinyl ether (PMVE) produces methylfluoroalkoxy (MEA) resins. [Pg.74]

Perfluoroalkoxy resin (PFA) Copolymer of tetrafluoroethylene (TFE) with perfluoro(propylvinyl ether), an engineering thermoplastic characterized by excellent thermal stability, release properties, low friction and toughness. Its performance is comparable to poiytetrafluoroethylene (PTFE) with the difference that it is melt processible. [Pg.201]

Fluoroplastics are a class of paraffinic polymers that have some or all of the hydrogen replaced by fluorine. These include polytetrafluoroethylene (PTFE), fluorinated ethylene propylene (FEP) copolymer, perfluoroalkoxy (PFA) resin, polychlorotrifluoroethylene (PCTFE), ethylene-chlorotrifluoro-ethylene (ECTFE) copolymer, ethylene-tetrafluoroethylene (ETFE) copolymer, polyvinylidene fluoride (PVDF), and polyvinylfluoride (PVF) [186],... [Pg.292]
