What is DMD?
The abbreviation “DMD” stands for Dacron-Mylar-Dacron composite insulation material which is formed using three materials; the center layer is made of Mylar (polyester film), while two outer layers consist of Dacron (polyester) non-woven fabrics. Thus, the insulating properties of Mylar and mechanical strength of Dacron allow creating a very good insulating material.
DMD composite materials may be found in form of sheet, roll, or cable wrap, and are used as an insulation material in electric motors, transformers, and other electrical devices requiring light flexible insulation material.
