Polyurethane Wire Enamel

Polyurethane Wire Enamel

Polyurethane Wire Enamel are known for smaller coefficient of friction, higher mechanical intensity, excellent heat resistant and good solderability. Basically the Enameled wire is a wire coated with a thin layer of insulation to prevent the wire surfaces from being in a short circuit when wound into coils. So whenever electric current passes through the wire or coil magnetic flux is created.
