High Temperature Polyimide Film PI Film Light Brown Insulating Film Liner Insulation
roduct name: polyimide film
Polyimide film has excellent comprehensive performance, in the present commonly used occupies a unique place in the electrical insulation film, it has excellent heat resistance and excellent cold resistance, in - 269 ℃, + 400 ℃ temperature range of its operating characteristics, but also has excellent electric insulation, radiation resistance, corrosion resistance and self-lubricating properties, thus has been widely used in operating conditions, high reliability requirements of all kinds of motors, electrical appliances and wire and cable, such as aircraft, spacecraft, nuclear industry, nuclear submarines, electric locomotive, petrochemical industry, electronic chemicals, including liquid crystal display (LCD) and plasma electronics, mobile phones, computers and digital drive applications.This company produces the film in addition to the commonly used specifications, thickness, ultra wide film for production.
Thermoforming PI film: TPI but molding polyimide film is a special kind of polyimide film, the thickness range 0.025 0.125 mm.
PI film can be heat molding scope of work for a long time - 260 ℃, 260 ℃, is a kind of excellent high temperature resistant film material, with high insulation, excellent mechanical properties, chemical stability and radiation resistance and self-extinguishing, fire rating 94 V - 0, product environmental protection without halogen, heavy metals and other restrictions on organic matter content meet the national environmental protection standard.
Thermoforming PI film: TPI to molding polyimide film appearance of transpa
Special performance: TPI to forming of polyimide film has lower glass transition temperature (250-260 degrees), ease of thermoforming.After molding, and the material of high rigidity, sound is ringing.Abroad used in the production of more advanced high fidelity of high-power stereo equipment of the diaphragm.
PI film performance can be heat molding parameter table (Property Parameter Table):
