Description
6630-B DMD Insulation Paper is a high-performance composite material engineered for demanding electrical insulation applications. It is widely recognized for its balanced dielectric, mechanical, and thermal properties, making it a preferred choice for motor and transformer insulation.
We also supply F Class DMD insulation paper: 6641-F DMD insulation paper
Composition & Manufacturing Process
6630-B DMD is manufactured using a precise lamination process that combines three distinct layers:
D-Layer: Polyester non-woven fabric
M-Layer: Polyester film (Mylar/PET film)
D-Layer: Polyester non-woven fabric
The middle layer is a polyester film, and the outer layer is a polyester fiber nonwoven fabric, forming a three-layer structure of "film-adhesive-nonwoven fabric".
Performance Advantages:
The unique three-layer structure provides 6630-B DMD with outstanding comprehensive properties:
1.Excellent Electrical Properties: The central polyester film layer ensures high dielectric strength and reliable insulation resistance, effectively preventing electrical breakdown 2.Good Mechanical Strength: The dual non-woven fabric layers provide exceptional tear resistance, tensile strength, and durability, withstanding rigorous manufacturing processes
3.Thermal Stability: Rated for Class B (130°C) temperature applications, maintaining performance under continuous thermal stress
4.Superior Impregnation Capability: The porous non-woven layers allow excellent penetration of varnishes and resins during vacuum pressure impregnation processes
Application:
6630-B DMD Insulation Paper finds extensive use in various electrical applications:
★Motor Insulation: Widely used as slot liners, phase insulation, and turn-to-turn insulation in electric motors
★Transformer Applications: Serves as inter-layer insulation in dry-type transformers and other electrical transformers
★General Electrical Equipment: Used in generators, alternators, and various electrical appliances requiring reliable insulation

Quick Answers for You
Quick answers to your pressing questions.
Q: How do you ensure consistent quality from batch to batch?
A: We control key parameters such as thickness, dimensions, dielectric performance, mechanical strength and moisture according to the product specification. Batch inspection and traceable test records help maintain consistent performance for repeat orders.
Q: Can you provide samples for testing?
A: Yes. Samples can be provided for material evaluation, testing or production trials. For customized materials, sample availability and lead time depend on the required specification.
Q: What technical documents can you provide?
A: Depending on the material, we can provide ISO, TDS, RoHS, REACH, SGS reports and relevant IEC or UL information for technical evaluation and supplier approval.
Q: What are your MOQ, lead time and shipping options?
A: MOQ and lead time vary by material, specification and processing requirement. Low MOQ and trial order can be accept accordingly. We support international shipments by sea, air and express courier.
Q: Are you a trader or manufacturer?
A: Chengrui combines our own manufacturing capabilities (flexible laminates, insulation sleeving etc) with a qualified partner production network. This allows us to supply a broader range of electrical insulation materials while maintaining specification control, quality inspection and technical support.
