Description

Brief Introduction of the Polyimide Film

Polyimide films provide excellent electrical, thermal, physical and chemical properties over a wide temperature range in a lightweight package (136 sq ft/lb [28 m2/kg] for 1 mil) making them superior for electrical insulation applications.
Polyimide film has the best thermal properties of films available.
—It has no melting point and can be used over a temperature range of -269°C to 350°C (-450°F to 660°F).
—It can be used constantly at a temperature of 240°C (465°F).
—Its physical properties are excellent and include high tensile strength, high resistance to creep, cut-through, abrasion, solvents and chemicals.
—It has high dielectric strength which makes it an ideal insulating material for use with high voltage. Polyimide film will resist radiation and ultraviolet light.
—It is flame retardant rated as UL 94 V-O.
