Kapton® FWN magnet wire insulation
Kapton® FWN is ideal for demanding magnet wire applications and for difficult-to-wind motors.
Kapton® FWN 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. Kapton® FWN is ideal for demanding magnet wire applications and for difficult-to-wind motors.
