Properties and Applications:

DMD70 is made from two-layer polyester nonwovens and electrical-grade polyester film laminated with F-class adhesive system, with good mechanical strength, electrical properties, reliable thermal stability, best combination of quality and price, flexible and high tearing strength, it is quite suitable for slot insulation. In addition, its excellent thermal resistance and compatibility approved by the Authoritative Testing Organization of our country, so it is long-workable for insulation in F-class motors as slot insulation, layer insuation, liner insualtion, such as, Y2 series of motors , its derived motors and other F-class motors and electric equipment etc.
