Norton® ECTFE  fluoropolymer film is manufactured from ethylene-chlorotrifluoroethylene (Halar®)* resin by Saint Gobain Advanced Films and Fabrics. This material offers the outstanding performance of fluoropolymer film over a temperature range from cryogenic -200°C (-328°F) to 165°C (330°F).

ECTFE film provides the highest abrasion resistance of any fluoropolymer film available. This film has superior chemical resistance and very high tensile strength and flexural modulus.

ECTFE film offers low surface energy, making it an excellent choice for release applications. The low specific gravity of ECTFE provides more square feet than FEP for composite fabrication.

The combination of heat stability, electrical characteristics and barrier properties provides insulator performance especially suited for the electrical and electronics industry. ECTFE film offers the highest dielectric strength of all fluoropolymer films.

ECTFE film has outstanding resistance to weathering and high energy radiation. This material is suitable for electrical tapes, cable insulation, printed circuits capacitors, chlorine cells, flat cable constructions and solar collectors.

ECTFE offers a UL V-0 rating for flammability. This provides performance suited for aircraft cabin interiors and fuel cell membranes. (see below)
