Blow Molding Fep Film UV Resistance Clear Polyimide FEP Film
Blow Molding Fep Film UV Resistance Clear Polyimide FEP Film
lExcellent thermal stability: Usable throughout a wide thermal range -200 to +200°C (-328 to +392°F)
lChemical Inertness: Resists almost all chemicals, such as strong acid, strong alkali, salt, and organic solvent.
lAnti-stick property: The lowest surface energy of all plastic films; displays excellent mould release and anti-stick properties.
lElectrical 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.
l Resistance to weathering: Inert to outdoor exposure; with unchanged mechanical and physical properties after 10 years.
l Non-flammability: Will not burn in air or gas having an oxygen concentration of less than 95%.
lHigh transparency: Transparent, with excellent transmission of ultraviolet rays and visible rays; lowest refractive index of all plastic films; characterised by very low light reflection.
