           DMD70 (Unsaturated, F-class)      

Properties and Application:

DMD 70 is made of two layers of electrical polyester non-woven and one layer of electrical grade polyester film, laminated

with a high temperature adhesive system, 70% filled with resin(unsaturated), with good dielectric properties, high heat

 resistance and mechanical strength, suitable for small and medium size electric motors as slot, phase, turn-to-turn, liner

insulation in F-class Motor. The ˇ°Flexible Typeˇ± is more flexible than ˇ°Standard Typeˇ± in mechanical property but with lower

Breakdown Voltage than ˇ°Standard Typeˇ±
