POLY(ETHYLENE-ALT-CHLOROTRIFLUOROETHYLENE)

POLY(ETHYLENE-ALT-CHLOROTRIFLUOROETHYLENE) Chemische Eigenschaften,Einsatz,Produktion Methoden

• Chemische Eigenschaften

  ECTFE has thermal and oxidative stability up to 150–175 ° C. It is chemically inert to a number of chemicals and solvents and has good permeability resistance. The copolymer is 50–55% crystalline, depending on the method of preparation.

• Chemische Eigenschaften

  Chlorotrifluoroethylene-ethylene copolymers (ECTFE) contain about 50 mole % chlorotrifluoroethylene. These copolymers are generally similar to the tetrafluoroethylene-ethylene copolymers in that they are melt-processable and have high impact strength and good chemical resistance. The temperature range of useful performance is from about - 80°C to 170°C. Chlorotrifluoroethylene-ethylene copolymers find use in injection mouldings for chemical process equipment and cable insulation.

• Verwenden

  Wire and cable insulation is the primary application of ECTFE.

• Vorbereitung Methode

  PCTFE is a polymer of chlorotrifluoroethylene. Copolymerization of ethylene and chlorotrifluoroethylene is carried out by aqueous suspension techniques, by low-temperature polymerization initiated by oxygen-activated triethylboron in dichlorotetrafluoroethane, and by radiation-induced polymerization.
