Polyimide film Covered Aluminum wire
Polyimide Kapton Covered /Enameled/ Insulated/ Wrapped Aluminum Wire Strip
Polyimide film aluminum wire is a multi-layer polyimide & fluoropolymer dispersion-coated film. The fluoropolymer coating functions as a heat-fusible layer for bonding to magnet wire conductors. It has superior scrape abrasion resistance and exhibits lower frictional properties than wire insulated with other commonly used polyimide materials. Polyimide film aluminum wire is ideal for demanding magnet wire applications and for difficult-to-wind motors.
