6643 F-class DMD （DMD100）flexible composite insulation paper

Short Description:

6643 Modified Polyester film/polyester non-woven flexible laminate is a three–layer 100% saturated flexible composite insulation paper in which each side of the polyester film (M) is bonded with one layer of polyester non-woven fabric (D), then coated with F-class electrical insulating resin.  6643 DMD is used as slot insulation, interphase insulation and liner insulation in F class electric motors, especially suitable for mechanized inserting slot process. 6643  F-class DMD has passed SGS test for toxic and hazardous substance detection. It is also called as DMD-100, DMD100 insulation paper.
