Product description of polyester film/non-woven polyester f DMD 6641 

6641 F-DMD is a three-layer flexible composite material, produced by using F-class adhesive to adhere the two faces of high-melt-point polyester film (Mylar) with hot rolling non-woven polyester fabric (Dacron) .

6641 Polyester film/polyester fiber non-woven fabric flexible    composite material (F-DMD) is made from high melting point polyester film and hot-rolling polyester fiber non-woven fabric. The polyester film and polyester non-woven fabric are bonded by F-class adhesive.

6641 Class F Polyester Film/Polyester Fiber non-woven Fabric composite(F-DMD) is made from one layer of high melting point film and two layers of hot rolling polyester fiber non-woven fabric. These three layers of flexible insulation are bonded by class F adhesive glue.

Extensively used as primary insulation for Class F applications in the electrical industry, in particular for motors and transformers as slot insulation, phase barrier and interturn insulation.

Polyester film/non-woven polyester F DMD  General Material

Pre-impregnated DMD FILM (Class F)formed in the process of precuring the modified F-class DMD with impregnation of Hi-temp resistant Epoxy resin into B-stage by baking

Polyester film/non-woven polyester F DMD  Characters

Pre-impregnated DMD FILM is Class F(155°C)insulating material

Pre-impregnated DMD FILM has long shelf life at room temperature,low precuring temperature and time,showing excellent electrical insulation, bonding and heat-resistant properties.

Polyester film/non-woven polyester F DMD  Application

Pre-impregnated DMD FILM is used for liner insulation of copper foil (aluminum foil) low voltage coils in dry-type transformer and slot insulation and interphase insulation in B ~ F class motors and electrical appliances.

Special specification can be supplied according to customer request.
