Detailed Introduction

1.jpg

 • Features:

Polytetrafluoroethylene, film, and tape are made by machining polytetrafluoroethylene molded blanks. They have excellent dielectric properties, no aging, the best chemical corrosion resistance, and a wide range of strength for use. The film is an non oriented film, which is developed into oriented and semi oriented films through compression.

 

• Purpose:

Substrate seals and lubricating materials used in various media, as well as electrical insulation components used at various frequencies. Capacitor dielectric, wire insulation, electrical appliances
