Brand: CVS®

Description

It is whiter in color compared to mechanical grade PTFE, has better physical properties and retains flexibility in low temperatures. It is also a good electrical insulator, with high dielectric properties.

Application:

Extremely soft and formable, it is often used for chemical resistant seals and gaskets. This grade of PTFE is often used where mechanical properties are not the most important requirement.

Product Features:
  • High-temperature resistance
  • Extreme chemical resistance
  • Anti-aging, weathering resistance
  • Excellent electrical insulation
  • Very low coefficient of friction
