FEP Film

Catalog Number

ACMA00034223

Description

1. Excellent thermal stability: Usable throughout a wide thermal range -200 to +200°C (-328 to +392°F)
2. Chemical Inertness: Resists almost all chemicals, such as strong acid, strong alkali, salt, and organic solvent.
3. Anti-stick property: The lowest surface energy of all Fluoropolymer films; displays excellent mould release and anti-stick properties.
4. Electrical reliability: High electrical insulation characterised by low-dialectic constant and dissipation factor and by high dialectic strength over a wide range of temperature and frequency.
5. Resistance to weathering: Inert to outdoor exposure; with unchanged mechanical and physical properties after 10 years.
6. Non-flammability: Will not burn in air or gas having an oxygen concentration of less than 95%.
7. High transparency: Transparent, with excellent transmission of ultraviolet rays and visible rays; lowest refractive index of all Fluoropolymer films; characterised by very low light reflection.
