6641-F DMD Insulation Paper For Motor Winding

6641-F DMD Insulation Paper is a high-grade polyester film and non-woven fabric composite material designed for demanding electrical applications, also called dacron mylar dacron insulation paper. The "DMD" designation represents its precise three-layer construction: two outer layers of non-woven polyester fabric (D) bonded to a central polyester film layer (M), using Class F adhesive system.

Chengrui Insulation supplies DMD insulation paper for motor slot insulation, phase insulation, interlayer insulation, and dry-type transformer insulation, available in standard rolls, slit rolls, strips and die-cut parts. Common slitting widths can be customized according to motor slot size, with sample approval before batch production.

Manufacturing Process of DMD insulation paper:

6641-F DMD features an advanced manufacturing process with specialized materials

Base Materials: Two layers of polyester non-woven fabric (D) and One layer of polyester film (M)

Bonding Technology: Class F (155°C) rated adhesive system

Precision lamination under controlled temperature and pressure

Key Differentiator: F-grade bonding agents ensure structural integrity at elevated temperatures

Special thermal curing process enhances temperature resistance

Features of DMD (dacron mylar dacron)Insulation Paper:

1. Excellent Insulation Performance: DMD insulation paper possesses excellent electrical insulation properties, effectively isolating conductive parts of electrical equipment and preventing leakage or breakdown.

2. Chemical Corrosion Resistance: DMD insulation paper exhibits good chemical corrosion resistance, maintaining stable performance even in certain corrosive media.

3. Good Mechanical Strength: DMD insulation paper possesses good mechanical strength and abrasion resistance, capable of withstanding certain mechanical stress and wear.

4. High Temperature Resistance: DMD insulation paper exhibits good high temperature resistance. Grade F DMD paper typically withstands temperatures above 155℃, making it suitable for electrical equipment in high-temperature environments.

6641-F DMD Insulation Paper delivers exceptional thermal stability through its F-class adhesive technology, providing reliable performance in the most demanding high-temperature environments while maintaining excellent electrical and mechanical properties. 

Application: DMD( (dacron mylar dacron) composite insulation paper is used as slot liner, slot closure, phase and turn-to-turn insulation in electrical motors. It can be used as inter-layer insulation in transformers and other electrical appliances.

As a China-based electrical insulation material supplier, we provide DMD in rolls, sheets, slit tapes and customized cut parts for motor manufacturers, rewinding workshops and electrical equipment OEMs. For OEM production, we help confirm insulation class, roll weight, packaging, sample supply, and delivery details before mass shipment.
