DM is a two-ply laminate obtained by hot coupling of a non-woven polyester fleece to one side of an electrical type polyester film.
The fabric is coupled to polyester using a special heat resistant resin, which puts the material into thermal Class F at 155° C. It’s non-woven polyesters mats absorbs the resin during the impregnation process where else the polyester-ply adds dielectrical strength, stiffness, memory shape and snapback.
