Polyimide film for voice coil
It is a synthetic resin composed of pyromellitic dianhydride and 4.4-diaminodiphenyl ether.
It is produced by the 'salivation method', which has high temperature resistance, radiation resistance and excellent dielectric properties.
Color: golden yellow, brown, black
Length: can be customized according to requirements.
Width: can be customized according to requirements.
Characteristic: good flame resistance, fire retardant, high pressure resistance
Application:
Low voltage, high temperature, electrical insulation
Motor insulation: high and low temperature resistance, high thermal conductivity, radiation resistance
Industrial insulation: excellent insulation and dielectric properties, strong mechanical properties
Flexible circuit board: higher temperature resistance, stability, bonding strength, thinner, better folding resistance.
Microelectronics packaging and manufacturing field: hydrolysis resistance, light weight, excellent performance under sever conditions such as low temperature, high speed, dry friction and high wear.
