Detailed Product Description

 

Polyimide film for Speaker voice coil , Polyimide Voice coil film 

Polyimide film is synthesized by polymerizing PMDA and ODA in strong polar solvents through the process of forming film and imines treatment at high temperature.

Polyimide film Features and Applications:

Polyimide film belongs to class H kapton

Excellent physical, chemical, and electrical properties, atomic radiation resistant, solvent resistant, low & high temperature resistant.

Polyimide film performs successfully in the wide range of temperature as low as -452F(-269°C) and as high as +500F(+260°C). Because of its unique excellent properties, it is the ideal choice    among many applications.

 

Polyimide film is used in flexible prinyed circuits and as insulating materials of flat electric cables, electromagnetic wires and motors.

Available: In rolls, in stripsSpecifications
