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

6643 Modified Polyester film/polyester non-woven flexible laminate is a kind o fthree–layer 100% epoxy resin 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 flexible electrical insulation paper is used as the  slot insulation, interphase insulation and liner insulation in F class electric motors, especially suitable for mechanized inserting slot process. 6643 passed SGS test for toxic and hazardous substance detection. It is also called as F class DMD, DMD100, DMD-100 electrical insulation composite material for electric motors.

Product Features

With coated heat-resistant resin which encapsulates the inner polyester film & adhesive, thus 6643 has excellent heat resistance property, excellent mechanical properties, excellent electrical properties and higher thermal resistance.

Applications

With coated heat-resistant resin, its surface is more smooth. It is suitable for mechanized inserting slot process.

6643 is used for slot insulation, inter phase insulation and liner insulation in F class electric motors, especially suitable for mechanized inserting slot process.
