GENERAL PROPERTIESImidex® polyimide film is a high performance polymer which combines excellent physical, electrical, and mechanical properties at temperatures as low as -452°F (-269°C) and as high as +446°F (+230°C). Imidex offers good dimensional stability combined with excellent chemical resistance -- there are no known solvents.
Imidex® polyimide film is similar to DuPont Kapton® material. It is manufactured by Westlake Plastics Company from Aurum® polyimide resin.
Imidex® polyimide film is Amber in color.
TYPICAL APPLICATIONS wire and cable tapes formed coil insulation flexible printed circuit board substrates motor slot liners magnet wire insulation transformer and capacitor insulation magnetic and pressure-sensitive tapes tubing
AVAILABILITYImidex® thermoplastic polyimide is offered in a single grade in thicknesses from .001" to .040", in rolls up to 26"wide.
NOTE: LIMITED sample quantities are
available for engineering evaluation only.
