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.
용도
Wire and cable insulation is the primary application
of ECTFE.
생산 방법
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.
