The Electrical DMD Insulation Paper is flexible composite material 6630 DMD electrical insulation paper.This DMD insulation paper is a three-layer composite electrical insulation paper. It is laminated with two layers of polyester fiber non-woven fabric and a single layer of polyester film in the center. The structure is Dacron+Mylar+Dacron, so it is referred to as DMD.
