H Class Polyester

Composed of polyester film, coated on both sides with aramid paper (Nomex®), glued with synthetic thermosetting adhesive. It is used as an insulator for electric motor grooves, resistant to the rigorous winding process made by the machine, and can also be applied in high temperature transformers and insulation between winding phases.

It has high dielectric strength, excellent adhesion of impregnation varnish or drip resin to the laminate. Low moisture absorption, good thermal and chemical resistance
