Polytetrafluoroethylene film is made of polytetrafluoroethylene resin by moulding, sintering, cooling into blank, and then by turning and rolling. The film is an undirected film, and the non-directional film is a directional film. The undirected film is compressed by 1.1-1.8 times the semi-directional film. Polytetrafluoroethylene (ptfe) color film is made of polytetrafluoroethylene (ptfe) resin mixed with the desired color, and then it is pressed, sintered, cooled into blank, and then rolled and rolled. There are semi - directional and non - directional films.
Polytetrafluoroethylene film directed film is used to make capacitors; The semi-directional film is used for conducting wire insulation; Non-directional film for electrical instrument radio insulation; As a pad material, it can also be used as a degumming and stripping material.
