Kapton Covered /Enameled/ Insulated/ Wrapped Aluminum/Copper Wires Strips

Kapton Enamel Wire——Amulti-layer Kapton & fluoropolymer dispersion coated film
Kapton Enamel Wire adopts high-quality F46 Polyesterimide layer and finishs through high heat sintering.
Kapton Enamel Wire’s temperature can reach 290℃ and its voltage class can be 7200v.
Special processing technology makes the product have high mechanical properties, stronger overload capacity,
heat-resistant properties and suitable for large and medium-sized motor coils and winding of electrical appliances
Kapton Enamel Wire is ideal for demanding magnet wire applications and for difficult-to-wind motors.
Kapton Enamel Wire also is a multi-layer Kapton & fluoropolymer dispersion-coated film.
The fluoro polymer 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 Kapton materials.

Product Introduction:
    This product is on the high quality aluminum conductor on the uniformity of the Kapton fluorine 4.6 composite film, after heating the composite film on the fluorine 4.6 melt, so that the coating and the conductor, film bonding between a whole. The product has excellent resistance performance voltage, temperature resistant grade for class H 220℃, resistance to high temperature and radiation, is winding volume small, high output, high reliability of electrical products the ideal winding line varieties.
