Colored PTFE film
It is made of suspended PTFE resin by molding, sintering, cooling into a blank, and then turning and calendering. The turned film is a non-oriented film, and the non-oriented film becomes an oriented film after being calendered. Non-oriented films are calendered 1.1-1.8 times for semi-oriented films. PTFE film is used as capacitor medium, wire insulation, electrical instrument insulation, and sealing gasket. PTFE film is divided into PTFE color film, PTFE activated film and F46 film.
