100% Virgin Teflon Film, PTFE Film


Product Detail


Product Description
100% Virgin Teflon Film, PTFE 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. They can also become insulating pieces under various frequencies, a capacitor medium, conductor insulator and insulation for electricity meters.
