PIW 240 grade polyimide enamelled copper wire

Enameled wire is an indispensable material in modern society such as vibrant electrical appliances, electronic machines, motors, transformers, relays and even automotive parts. Chalco has various types of enameled wires, including enameled aluminum wire, enameled copper wire, enameled copper clad aluminum wire, high-tension wire, magnetic wire, stranded wire, etc. Chalco's special enameled flat wire is suitable for high-precision coils and has won the trust of the industry.

PIW 240 grade polyimide enamelled copper wire

PIW is a polyimide resin with the highest heat resistance of an organic polymer made by the reaction of aromatic tetracarboxylic acid dianhydride and aromatic diamine for enameled wire. PIW is a very reliable performance because it has excellent through characteristics, overload characteristics and thermal shock resistance.

Characteristics of PIW 240 grade polyimide enamelled copper wire:

High heat resistance; superior chemical resistance

Application:

High heat resistant components; high power motor
