Composition：

It’s an enamelled strip with excellent mechanical, thermal and chemical properties. Structurally, the insulation consists of a POLYESTER or POLYESTER-IMIDE-based varnish and a POLYAMIDE-IMIDE top layer. Each layer of varnish gives the final wire excellent properties, including excellent abrasion resistance, high flexibility and adhesion to copper, which means it is able to withstand the extreme deformation, stretching and crushing that occur during winding…
