Ethylene Tetrafluoroethylene Copolymer Chemische Eigenschaften,Einsatz,Produktion Methoden
Chemische Eigenschaften
ETFE is an alternating copolymer of tetrafluoroethylene and
ethylene similar in properties to polytetrafluoroethylene, but
it has higher impact and tensile strengths. Other properties
include low dielectric constant, excellent resistivity, and low
dissipation factors. Thermal and cryogenic performance and
chemical resistance are rated as good.
Verwenden
ETFE is used in thin
coatings, heavy wall logging cables, insulation, tubing, and
fasteners.
Vorbereitung Methode
To prepare ETFE, ethylene and tetrafluoroethylene are copolymerized
in aqueous, nonaqueous, or a mixed medium with
free-radical initiators. The polymer is isolated and converted
into extruded cubes, powders, and beads.
