Tetrafluoroethylene-Perfluoroalkoxyethylene polymer (PFA) Film
PFA film is made from PFA resin and prepared by the technology of thermoplastic extrusion and blowing. It has non-sticking, heat-resistance, aging resistance, corrosive resistance, non-flammability and good electric property. It can be solid adhesive for PTFE and also a good adhesive for laminating various materials. Its working temperature is up to 260℃ and is an ideal material for circuit board and flat cable. It conforms to the enterprise standard of Q/GHAD 11-2005.
