Product Description

Product Description

PTFE Film (polytetrafluoroethylene film) is an extremely thin, soft film material made of polytetrafluoroethylene (PTFE) resin with extremely high chemical resistance and electrical insulation. It is often used in high-end industrial scenarios such as electrical insulation, corrosion-resistant lining, sealing, lubrication isolation, etc.

It is an important extension form of PTFE material, usually made by calendering, stretching or sintering.

FAQ

1/ What is PTFE film used for?
PTFE film is widely used for electrical insulation, chemical resistance linings, anti-stick layers, and heat sealing applications. It is ideal for industries such as electronics, chemical processing, packaging, medical, and aerospace.

 
2/What thicknesses are available for PTFE film?
We offer PTFE films in a wide range of thicknesses:
From 0.01mm to 1.0mm.
Ultra-thin options like 0.005mm are also available for special applications.

 
3/ Is PTFE film heat resistant?
Yes. PTFE film can operate continuously at temperatures up to 260°C (500°F) and withstand short-term exposure up to 300°C. It remains stable without melting or degrading.

 
4/Is your PTFE film FDA approved?
Yes. Upon request, we can supply FDA-compliant PTFE film for food contact or medical applications. Please let us know your intended use.
