The Insulation Solution


		Data Sheet

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 “Flexible Type” is more flexible than “Standard Type” in mechanical property but with lower

Breakdown Voltage than “Standard Type”
