ETFE Technical Information

Ethylene Tetrafluoroethylene (ETFE)

ETFE (Ethylene Tetrafluoroethylene) is a thermoplastic fluoropolymer based on an alternating copolymer of ethylene (C2H4)   and tetrafluoroethylene (C2F4).

Key Properties of ETFE Fluoropolymer

.  Chemical resistance
   ETFE  provides  excellent  resistance  to  virtually all chemicals and solvents that can cause rapid deterioration of other plastics.

.  Mechanical strength
   It has superior mechanical strength, stiffness and good resistance to stress cracking. It has a higher  tensile strength and greater crush resistance than other  fluoropolymers.  ETFE  also offers  a low  coefficient  of  friction  and  its  oil / water  repellency  renders  it an excellent coating material for low flow resistance.

.  Good electrical properties
   ETFE is an excellent insulator.

.  Non-flammable
  As tested by Underwriters Laboratories, ETFE has 94V-0 flammability rating, which according to ASTM D165, it is non-flammable.

.  Great weatherability
   It screens out ultraviolet (UV) rays but does not deteriorate as a result of exposure to UV.

.  Outstanding performance over a wide range of  temperature
   It is corrosion resistant, and has stable mechanical and electrical properties over a wide temperature range of -100°C to 150°C.
