Class B DMD (6630) Flexible Laminates
Polyester film with Non-woven fabric
In accordance with GB/T5591.3.1-2008 and IEC626-2.
Description:
Class B DMD Flexible Laminate is a three-layer flexible composite material, produced by using B-class adhesive to adhere the two faces of high-melt-point polyester film with hot-rolled non-woven polyester fabric (Dacron).
Advantages:
It has excellent electrical, mechanical, and impregnating properties.
Applications:
The Class B DMD is suitable for slot liner, slot closure, phase and turn-to-turn insulation in electrical motors. It can be used as interlayer insulation in transformers and other electrical appliances.
