Products Description
Insulating material 6630 DMD Insulation Paper technology is a soft composite material.
It is a three-layer insulating paper made of polyester film coated with adhesive and bonded with polyester fiber non-woven fabric (non-woven fabric) on both sides. Motor insulating paper DMD is a very Important motor insulation material, widely used in various types of motors. It can effectively protect the internal parts of the motor and prevent circuit short circuits and other faults.
6630 Polyester film/ polyester fiber non- woven fabric flexible composite material ( DMD) consists of two Layers of Polyester Fiber Non- woven Fabric and a single layer of Polyester Film in the center
DMD thickness: 0.18mm-0.30mm

Why Is DMD Still Widely Used in Motor Manufacturing?
Although newer insulation systems are available, 6630 DMD remains one of the most economical and practical choices for Class B motors.
The polyester film provides electrical insulation, while the non-woven outer layers improve flexibility and help the material absorb insulating varnish during impregnation. This combination makes it suitable for both manual winding and automated production processes
