Products Description

Composition:
PM is a two layer flexible insulation material, consists of brown-yellow insulation paper and polyester film. The used adhesive is acid free and temperature resistant.

Application:
PM is used as slot liner, phase insulation for low voltage motors or other electrical machines application.

Performance:
PM 50 has excellent electrical and mechanical properties.

Storage:
Under normal conditions (20℃,50% relative humidity), can be stored indefinitely
