Introduction
The 6641 DMD mylar polyester film electrical insulation material is a three-layer composite material made of one layer of polyester film and two electrical polyester fibre nonwovens and glued by F class resin. With good mechanical property and electrical property, polyester non-woven fabric has good adsorption capacity and can absorb resin during impregnation.
Application
It is widely used in slot, phase and liner insulating of motors,Interlayer insulation in the transformer. It is also widely used in automatic coil inserting machine for wedge inserting.
