GENERAL PROPERTIES Imidex® 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
AVAILABILITY Imidex® 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.
Manufacturer stock levels have not been established.
