Mylar / Dacron Electrical Insulation Paper Roll For Motor Winding
Insulation Paper for Motor WindingDacron/Mylar/Dacron Electrical insulation paper DMD 515 different thickness and color
roperties and Application:
DMD is made of two layers of electrical polyester non-woven (PET-fleece) with one layer of polyester film, with excellent dielectric properties, high heat resistance and mechanical strength, which is suitable for small and medium size electric motors as slot, phase, turn-to-turn, liner insulation in B-class motor. The “Flexible Type” is more flexible than “Standard Type” in mechanical property but with lower Breakdown Voltage than “Standard Type”.
