Mica/Polyester Insulation

Mica-Polyester compounds generally comprise Mica paper on which a polyester film coat (PETP) is spread using an epoxide resin.

Mica paper is a type of paper composed only of small strips of Mica with no admixture or bonding material (100% Mica).

The above materials are of thermal class 155° and are used as insulation for high voltage motor/generator windings
