4.Insulating Varnish for our enameled wire to guarantee quality.


ELANTAS Electrical Insulation are enamels used for manufacturing of magnet wires.

They are coated on the surface of copper or alumina wires and cured to form electrical insulation film possessing certain mechanical strength, thermal resistant and chemical resistant properties. Some products could be used for other applications such as metal wires for decoration purpose and other insulating or thermal resistant coatings.


Our products are classified in the following categories based on main

polymers and applications:

1.Polyvinylformal Enamels

2.Polyurethane Enamels

3.Polyesterimide Solderable Enamels

4.Polyesterimide Enamels

5.Polyester Enamels

6.Polyamideimide Enamels

7.Polyimide Enamels
