PTFE film for electrical insulation

PTFE electrical insulation film is used for:

  • High voltage cable insulation
  • Critical electronic components
  • Battery applications
  • Power modules
  • Harsh chemical environments
  • High-temperature exposed systems

Its dielectric strength and thermal stability make it a strategic solution in critical environments.

High-temperature PTFE film is recommended when:

  • The environment is chemically aggressive.
  • The operating temperature is high
  • The dielectric strength must be constant
  • Solvent resistance is critical

Unlike polyester or polyolefin films, PTFE fluoropolymer film retains its properties in extreme conditions.

What is PTFE film?

PTFE film (polytetrafluoroethylene film) is a fluoropolymer recognised for:

  • Near-universal chemical resistance
  • Excellent temperature control
  • Low coefficient of friction
  • Stable dielectric properties
  • UV resistance and resistance to aggressive environments
  • Low moisture absorption

PTFE insulating film is particularly suited for applications requiring maximum chemical and thermal inertia.

PTFE vs PEEK or polyimide film: what's the difference?

The PTFE film is distinguished by:

  • Superior chemical resistance
  • Low coefficient of friction
  • Exceptional chemical inertness

PEEK offers better mechanical resistance.

Polyimide excels in stable thermal resistance.

The choice depends on your application environment.
