6641-F DMD Flexible insulation paper
Description: Class F DMD Flexible Laminate is a three-layer flexible composite material, produced by using F-class adhesive to adhere the two faces of high-melt-point polyester film with non-woven polyester fabric.
Advantage: This material has comparatively good heat-resistance, dielectrical property and good mechanical property, along with sound soakage capability.
Applications: Class F DMD mainly used as 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.
