Soft Composite Insulation Material

Soft composite DMD insulation paper, full name polyester film polyester fiber non-woven soft composite foil, is a two-layer polyester non-woven fabric in the middle of a layer of insulated polyester film composite made of three insulation materials. DMD is divided into B-class and F-two, B-class temperature of 130 degrees, F-class temperature of 155 degrees. B-level in the Chinese market is white, F-class products are usually blue or pink, to distinguish between. DMD products in the appearance of the appearance of a smooth, no bubbles, creases are better for the motor slot insulation and liner insulation.
The soft composite insulating material is made of one or both sides of the film. The structure of the insulating paperboard, glass cloth, synthetic fiber paper, etc., or both sides is the film, the middle is the structure of the asbestos paper and the glass cloth. The role of the electrical insulating board and other fibrous materials Is to increase the mechanical strength and stiffness of the film, to maintain good flexibility and improve heat resistance. Fiber paper has excellent adsorption, and the groove wall and the coil has a good adhesion between, to avoid displacement when running. Excellent dielectric properties, can compensate for the lack of dielectric strength of fiber paper, the composite soft material, to meet the dielectric properties, mechanical properties and application process performance requirements for motor, electrical appliances, transformers and household appliances, electronic equipment The insulation of the slot insulation, wire insulation and liner insulation. The use of soft composite insulation material, can reduce the thickness of insulation, reduce the size of the motor, increasing the insulation reliability.
