Overview
Thermally Bondable Polyurethane Enameled Wire features polyurethane insulation with a self-adhesive outer layer that melts under heating to bond windings firmly without extra adhesives. It delivers superior solderability, allowing fast soldering without stripping the film, greatly improving winding efficiency for miniature coils.This wire boasts thin, uniform enamel film and stable dielectric strength, effectively avoiding insulation breakdown during tight winding. Its smooth surface fit compact motor, transformer and inductor designs for electronics, automotive and communication devices.With good heat resistance and flexibility, it withstands repeated bending without film cracking. The self-bonding property secures coil structure, reduces coil loosening noise and enhances product stability, ideal for high-density, miniaturized electromagnetic components.

Specification

Product Features

Thermally Self-bondable Polyurethane Coating: The outer adhesive layer melts upon heating to bond coils tightly without additional glue, locking winding shape and eliminating coil vibration noise.

Excellent Direct Solderability: Polyurethane enamel can be soldered directly without film stripping, cutting coil processing time and simplifying production workflows.

Stable Insulation & Compact Structure Adaptability: Uniform thin enamel ensures reliable dielectric strength. It support high slot fill rate miniaturized winding designs

Superior Mechanical Flexibility: Flexible copper conductor paired with crack-resistant PU film tolerates repeated tight bending during winding, preventing insulation damage and extending service life
