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]

Extrusion-Applied Insulations. The polymers used in extrusion applications can be divided into two classes low-temperature applications and high-temperature applications. Polymers in the first category are poly(vinyl chloride), polyethylene, polypropylene, and their copolymers along with other elastomers. Polymers in the second category are mainly halocarbons such as Teflon polytetrafluoroethylene (which requires special extrusion or application conditions), fluoroethylene-propylene copolymer (FEP), perf luoroalkoxy-modified polytetrafluoroethylene (PFA), poly(ethylene-tetrafluoroethylene) (ETFE), poly(vinylidene fluoride) (PVF2) (borderline temperature of 135 °C), and poly(ethylene-chlorotrifluoroethylene). Extrusion conditions for wire and cable insulations have to be tailored to resin composition, conductor size, and need for cross-linking of the insulating layer. [Pg.523]

Fluoropolymers. Melt processable fluoropolymers such as Teflon FEP, Tefzel ETFE, poly(vinylidene fluoride) (Kynar), and ethylene-chlorotrifluoroethylene copolymer (Halar) are suitable for wire insulation in special applications because they combine good physical properties with low flammability. They are used for instrumentation cable in process-control rooms, as well as for computer and aircraft wiring and in military applications. The... [Pg.524]

Copolymers of ethylene with tetrafluoroethylene (ETFE) and chlorotrifluoroethylene (ECTFE) are mechanically stronger than perfluoropolymers, with some reduction in their chemical resistance and continuous use temperature and an increase in the coefficient of friction. [Pg.1031]

Polytetrafluoroethylene (PTFE Teflon) was discovered accidently by PlunkettCZ nd commercialized by DuPont in the 1940 s. This polymer has a solubility parameter of about 6H and a high melting point of 327°C and is not readily moldable. Poly-chlorotrifluoroethylene (CTFE, Kel-F), the copolymer of tetrafluoroethylene and hexafluoropropylene (FEP), polyvinylidene fluoride (PVDF, Kynar), the copolymer of tetrafluoroethylene and ethylene (ETFE), the copolymer of vinylidene fluoride and hexafluoroisobutylene (CM-1), perfluoroalkoxyethylene (PFA) and polyvinyl fluoride (PVF, Tedlar) are all more readily processed than PTFE. However, the lubricity and chemical resistance of these fluoropolymers is less than that of PTFE. [Pg.92]

Ethylene-tetrafluoroethylene copolymer (ETFE) is a linear macromolecule with the monomer unit [—(CHjlj—(CF l —] . ETFE exhibits physical properties similar to those of ethyl-ene-chlorotrifluoroethylene copolymer. [Pg.709]

The unit cell of alternating copolymers of ECTFE is hexagonal with a chain repeat distance of 0.502 mn.[57][58] pjjg (.gp contains three molecules and occupies a volume of 0.324 nm. f l The preferred morphology of ECTFE chains is similar to that of ETFE where chlorotrifluoroethylene units line up opposite ethylene in the adjacent chain. This structure has been credited for the relatively high melting point and physical properties of equimolar ECTFE. [Pg.19]

Chlorotrifluoroethylene (CTFE) can also be homo-and copolymerized by suspension and dispersion methods in aqueous andnonaqueous media. The copolymer of ethylene and CTFE is ECTFE, a melt processible polymer and a counterpart of ETFE. CTFE is also copolymerized with vinylidene fluoride (VDF). Higher VDF contents generate elastomeric polymers. Methods similar to those for PTFE are used to recover the polymer in various forms. Both powder and dispersion products are available. PCTFE can be processed by both non-melt techniques such as compression molding, and melt techniques such as injection molding and extrusion. Thicker parts are usually made by non-melt methods. [Pg.26]

The most important interpolymers (e.g., copolymers, terpolymer, etc.) are those made with tetrafluoroethylene (ethylene tetrafluoroethylene polymer, ETFE) and chlorotrifluoroethylene (ethylene chlorot-rifluoroethylene polymer, ECTFE). These two polymers are generally produced by suspension or emulsion polymerization methods. There is resemblance between the polymerization technology of ETFE and ECTFE. Indeed, some of the same patent art could be studied to learn about the technology. This section and the next one present the polymerization of ETFE (Sec. 5.7) and ECTFE (Sec. 5.8). [Pg.90]

The commercially important fluorocarbon polymers are poly(tetrafluoroethylene) (PTFE), poly(tetrafluoroethylene-co-hexafluoropropylene) (FEP), poly[tetrafluoroethylene-co-(perfluoroaJkylvinyl ether)] (PFA), and amorphous fluoropolymer (AF), typically copolymers of tetrafluoro-ethylene and fluorinated dioxole. The second group of fluoropolymers includes modified poly(tetrafluoroethylene-co-ethylene) (ETFE), poly(vinylidene fluoride) (PVDF) (sometimes referred to as PVF2), and copolymers of vinylidene fluoride, poly(chlorotrifluoroethylene) (PCTFE), poly(chlorotrifluorethylene-co-ethylene) (E/CTFE) and poly(vinyl fluoride) PVF.
