Copper Enamelled Magnet Wire | Grade 1 and Mica
Polyester 200 is a multi-purpose dual coated wire which combines the excellent physical and electrical properties of a polyesterimide or modified polyester base coat with the added smoothness and high thermal rating of a polyamide-imide linear polymer topcoat. The combination of these two high quality resins produce a coating which has outstanding surface toughness, abrasion resistance, flexibility, chemical resistance, burnout and thermal resistance and dielectric strength.

- Excellent winding characteristichs due to the
high resistance to abrasions and to the good
surface smoothness - Excellent thermal resistance (>200 °C)
- Very high resistance to impregnating varnishes and
to humidity - Very low percentage of extraction with
perchloroethylene with Danfoss method - Excellent resistance to transformers oil
