F-DMD(6641) Flexible Laminates

F-DMD(6641) Flexible Laminates are a family of 3- ply laminates of non-woven polyester fiber mat bonded to both sides of polyester film. As a result, it has good mechanical strength, dielectric property and reliable heat adhesivity, cost-effectiveness. It is a perfect insulating material for class-F electrical machines in slot, phase, liner. The temperature index is 155℃

Characters:

* Reliable mechanical strength and dielectric property

* Good flexibility and tear-resisting; good applicability in slot insulation

* Can be used for a long time in class-F insulation
