Class F(155oC)
Good mechanical properties
Absorbs well impregnation varnishes and resins
General descriptionDMD is composed of two layers of non-woven fabric and a layer of polyester film,with high heat-resistant adhesive for gluing pressing of three soft composite material.
ApplicationDMD is suitable for insulation in electrical motors and transformers with a maximum operating temperature of 155oC. It is used in low or medium voltage rotating machines as ground and slot insulation. It can be used as well as intermediate layer in transformers.
