6641-Polyester Film/Polyester Fibre Non-woven Fabric Flexible Composite Material (Class F DMD)

Product No.:MAL02

MAL02150/MAL02170/MAL02200/MAL02230/MAL02250/MAL02300/MAL02350

6641-Polyester Film/Polyester Fiber Non-woven Fabric Flexible Composite Material (Class F DMD) is made from high melting point polyester film and hot-rollig polyetser fiber non woven fabric. The polyester film and polyester non-woven fabric are bonded by F-class adhesive. It is Class F (155°C) insulating material. This product has high mechanical strength, excellent electrical property and immerse function.

H class DMD is designed for insulating and protecting electrical equipment. It offers excellent dielectric and varnish absorption characteristics while ensuring low moisture absorption. It is ideal for slot cell, phase and wedge insulation. The conjunction of the inorganic filled resin system and 2 layers of the polyester film make this laminate suitable for major high temperature applications. It exhibits optimized thermal conductivity, long term voltage endurance and coil bonding characteristics. The tear initiation and cut through resistant polyester film reinforcement are excellent for automatic insertion and heavy duty winding operations.
