Characteristic：Amorphous thermoplastic high temperature resistant film. (Can be used for a long time in the range of 160°C-180°C)

①Mechanical properties such as extremely high strength and modulus at elevated temperatures. Excellent dimensional stability. (low creep sensitivity, low and uniform coefficient of thermal expansion)

②Excellent insulating properties, stable dielectric constant (Dk) and low dissipation factor (Df) over a wide temperature and frequency range.

Excellent flame retardancy and low smoke generation, in line with ABD, FAR and NBS requirements.

③Excellent chemical resistance to most oils, detergents and disinfectants. Can withstand a variety of disinfection methods.

With visible light, infrared and microwave penetration.

The main application scenarios of PEI film: electronic and electrical industries with special requirements such as waterproof, dustproof and breathable, speaker diaphragm, high temperature supercapacitor, etc.
