Fluorinated Ethylene Propylene Copolymer Film

Product Overview

Description

Fluorinated Ethylene Propylene Copolymer Film

Thicknesses from 0.03mm to 0.3mm

* Excellent thermal stability: Usable throughout a wide thermal range -200 to +200°C

(-328 to +392°F)

* Chemical Inertness: Resists almost all chemicals, such as strong acid, strong alkali,

salt, and organic solvent.

* Anti-stick property: The lowest surface energy of all plastic films; displays excellent

mould release and anti-stick properties.

* 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.

* Resistance to weathering: Inert to outdoor exposure; with unchanged mechanical

and physical properties after 10 years.

* Non-flammability: Will not burn in air or gas having an oxygen concentration of less

than 95%.

* High transparency: Transparent, with excellent transmission of ultraviolet rays and

visible rays; lowest refractive index of all plastic films; characterised by very low light

reflection. Standard Specifications of FEP Film
