The family of FPs, also called fluorocarbon plastics, is based on polymers made of monomers composed of fluorine and carbon may also include chlorine atoms in their structure. Specific types include polytetrafluoroethylene (PTFE), polytetrafluoroethylene-cohexafluoro-propylene or fluorinated ethylene propylene (FEP), polytrafluoroethylene-coperfluoropropylvinyl ether (PFA), ethylenetetrafluoroethylene (ETFE). polychlorotrifluoroethylene (PCTFE), ethylene-chlorotri-fluoroethylene (ECTFE), polyvinylidene fluoride (PVDF), polyvinyl fluoride (PVF), perfluoromethylvinylether (PFMV), perfluoroalkoxy (PFA), etc. [Pg.73]

Primary or secondary fluorocarbon radicals formed from exposure of PTFE to an ionizing radiation source react with dioxygen to form perfluoroalkylperoxy radicals. These give rise to perfluoroalkoxy radicals which can then decompose as indicated below [790] ... [Pg.595]

Perfluoroalkoxy resin (PFA) n. A class of melt-processable fluoroplastics in which perfluoroalkyl side chains are cormected to the fluorocarbon backbone of the polymer through flexible oxygen linkages. [Pg.706]

The macromolecule of perfluorinated alkoxy (PFA) or simply perfluoroalkoxy is based on the monomer unit [—(CFj) —CF(0—C F, )—(CFj) —] . Perfluoroalkoxy is similar to other fluorocarbons such as polytetrafluoroethylene and fluorinated ethylene propylene regarding its chemical resistance, dielectric properties, and coefficient of friction. Its mechanical strength. Shore hardness, and wear resistance are similar to PTFE and superior to that of FEP at temperatures above ISO C. PFA has a good heat resistance from -200 C up to 260°C near to that of PTFE but having a better creep resistance. [Pg.708]

Perfluoroalkoxy (PFA) fluorocarbon resins are designed to meet industry s needs in chemical, electrical, and mechanical applications. These melt-processible copolymers contain a fluorocarbon backbone in the main chain and randomly distributed perfluorinated ether side chains ... [Pg.5468]

Perfluoroalkoxy is inert to strong mineral acids, organic bases, inorganic oxidizers, aromatics, some aliphatic hydrocarbons, alcohols, aldehydes, ketones, ethers, esters, chlorocarbons, fluorocarbons, and mixtures of these. [Pg.54]

Empirical studies have shown that poly(tetrafluoroethylene) (PTFE) and poly(vinyli-dene diflouride) (PVDF) can be of varying purity, often resulting in unexpected contamination problems in ultratrace analysis, whereas perfluoroalkoxy (PFA) fluorocarbon proved to be cleaner by origin, and consequently, acidic washing processes could be successfully applied. These different fluorinated polymers have been compared regarding their suitability for container or sampler material [10]. It has been found that PFA exhibits the lowest nanoroughness and hence seems best suited as container material. [Pg.6]
