Features

It is an enamelled wire with high mechanical, thermal and chemical properties. Structurally, the wire consists of a POLYESTER or POLYESTER-IMIDE base varnish and a POLYAMIDE-IMIDE top layer. Each layer of varnish gives the final wire excellent properties for the industry.

Mechanically, its stand-out features are its excellent resistance to abrasion, flexibility (meaning it is capable of withstanding demanding deformations, stretching and crushing in final processes), and low friction coefficient, which allows the wire to be worked on at high winding speed without damaging the insulating layer.
Thermally, the wire is capable of withstanding high working temperatures and occasional overloads. Chemically, the wire is compatible with most commercial impregnation resins and oils, coolants and cleaning fluids.

Despite being a complete wire, there may be applications that require a specific improvement, which is why we have a qualified technical team to study specific cases and prepare a project tailored to any need.
