1. Anti-voltage intensity
2. High breakdown voltage
3. A wide range of operation temperature
2.Description
Ptfe Teflon Film is made of die-pressed PTFE blanks and has excellent dielectric
performance and weathering. It is a non-orientated film and may be pressed to
become orientated or semi-orientated film, i.e. suede pads, seals and lubricating
materials in various media. Ptfe Teflon Film can also become insulating pieces under various frequencies, a capacitor medium, conductor insulator and insulation for electricity meters.
3.Advantages
1.Minimal Water Absorption
2.Excellent Machining
3.Acid and chemical resistant
4.Good Electrical insulation
5.High working temperatures
6.Low friction
7.Surface protect material
