6630-B DMD Insulation Paper Introduction
This DMD insulation paper is a three-layer composite electrical insulation paper. It is laminated with two layers of polyester fiber non-woven fabric and a single layer of polyester film in the center. The structure is Dacron+Mylar+Dacron, so it is referred to as DMD.
It has good dielectric and mechanical properties, high tensile strength, and heat resistance. Suitable for Class B (130℃) as slot insulation and linear motor, electrical insulation, and turn-to-turn insulation.
Thickness:0.15mm-0.4mm
Width:1000mm or customized
Color: White, green, blue, and pink
Insulation Class: B class (130°C)
6630-B DMD Insulation Paper Features:
1. Excellent electrical properties
2. High tear, tensile, and burst strength
3. Retained flexibility
4. Physical Toughness
5. Excellent moisture and chemical resistance
6630-B DMD Insulation Paper Applications:
It is for B-grade motors, generators, or other electric appliances, as slot, intern, phase, and liner insulation.
