The film chopped by a machine car is a nondirectional film, which turns into a directional film after pressed and delayed. The nondirectional film is 1.1-1.8 times of the semi-directional film. PTFE film is used for capacitor medium, conductor insulation, electrical instrument insulation and dense pad. Because of its high crystallinity, tight molecular orientation and small void ratio, the PTFE Film is greatly improved.
Polytetrafluoroethylene film is divided into polytetrafluoroethylene color film, polytetrafluoroethylene activation film and F46 film.
Polytetrafluoroethylene color film is a kind of directional or non-directional color film of polytetrafluoroethylene, which is made of suspension polytetrafluoroethylene resin and added with a certain amount of colorant, then molded and sintered into blank, and then turned into red, green, blue, yellow, purple, brown, black, orange and white. Polytetrafluoroethylene color film has good electrical insulation after adding a certain amount of colorant and is suitable for insulation and classification of wires, cables and electrical components.
Polytetrafluoroethylene activation film is a kind of film which is made of polytetrafluoroethylene film, filling film and color film, and then treated by surface activation. Pigment, glass fiber, carbon fiber, graphite, bronze powder and other fillers are added into the products, and the properties are further improved after activation treatment. It can be compounded with rubber, metal and other materials, and can also be used to make the special tape, meeting the requirements of the design. It is widely used in light industry, military industry, aerospace, oil field and other fields.
F46 thin film has the most obvious anti voltage strength and breakdown voltage. Used for capacitor medium, conductor insulation, electrical instrument insulation, sealing gasket. Polytetrafluoroethylene (Teflon) turning film is a kind of directional film formed by hot roll rolling of the calender. It has high crystallinity, tight molecular orientation and small void ratio. Therefore, the PTFE film has been greatly improved, especially voltage strength.
