Product Description

DMD FILM

Properties

F-DMD (6641) is made of two layers of non-woven laminated with one layer of polyester film, the different ofDMD and F-DMD is on the adhesive resin, DMD use the resin of class B while F-DMD use the resin of classF. It has good dielectric properties, high heat resistance and mechanical strength, is suitable for small and medium size electric motors as slot, phase, turn-to-turn, liner insulation of class F.
