Features

This wire has excellent mechanical, thermal and chemical properties.
Structurally, the wire consists of a single layer of POLYAMIDE-IMIDE varnish.

Mechanically, it is characterised by its excellent resistance to abrasion.
Thermally, it is a wire capable of withstanding continuous high working temperatures and occasional overloads.

Chemically, the wire is compatible with most commercial impregnation resins and oils, coolants and cleaning fluids.
