6630 DMD has three layers: two layers of polyester fiber non-woven fabric and a single layer of polyester film in the centre (Compositions of Dacron “D” + Mylar “M” and Dacron “D” – DMD). It has excellent dielectric and mechanical properties, high tensile strength and heat resistance.
We supply three thickness: 0.20mm, 0.25mm, and 0.30mm. Standard weight per each roll is 95 to 110kg.

| Standard package: |
each roll is packaged with two layers of protection, one is a thick layer of corrugated fiberboard and inside is a layer of transparent nylon. Each side (or each ‘head’) of the roll is protected by a corrugated fiberboard cap to prevent damage, dent or sunken to the product. Each roll is packaged to ensure quality and appearance remain unchanged during transportation. The roll's nominal width is 100 centimetres (1 metre), height is 36 centimetres. |
| Minimum order quantity: |
Minimum one roll of 50 kgs. All film and paper insulation materials sold at Hoang Khanh are measured in kilograms, not metres. The reason is that depending on the thickness and for the formulation of the film, the standard grammage density may vary. This means 100 metres of a 0.30 mm film may be heavier than 100 metres of a 0.10 mm film. Not to mention the difficulty in measuring these in metres. Putting a roll of 100 kgs on a scale is definitely faster and more efficient than using a ruler and measure 100 metres of a product. |
| Cutting service: |
We can cut (slit) the products using a specialised cutting machine as required. Please send pictures of finished products and cut specifications for further advice. Learn more > |
| Outer appearance: |
Both sides are rugged because this product is a triple-layer insulation product, in which the MYLAR layer (made of the polyester film) is in the middle of two DACRON layers. These two layers are made of non-woven fabric. Therefore, with normal vision, you cannot see the polyester film in between. The surface of the material is smooth and it can be easily processed in automated insulation machines (no resin abrasion). In spite of the smooth surface, impregnating resins bond very well with this product. |
| Application: |
Its excellent dielectric properties make it particularly suitable for applications in the field of electric insulation, suitable for slot liner, slot closure, phase and turn-to-turn insulation in electrical motors. It can be used as interlayer insulation in transformers and other electrical appliances. With DMD, the sensitive polyester film is protected at high temperatures against the damaging effects of oxidation and hydrolysis as well as mechanical damage, thanks to the two nonwoven layers. The subsequent securing of the windings using immersion, drip or vacuum impregnation poses no problems when using DMD. |
