Used for electrical insulation, DMD Composite Paper is economical and versatile. This material is made from a single layer of polyester film that is coated on both sides with polyester felt. This three-layer constructions ensures the material offers good mechanical and dielectric strength while still being able to be impregnated by insulating varnishes.
DMD Electrical Insulation Paper is available in a selection of thicknesses. More information on these as well as it’s performance traits and benefits, is provided below:
DMD’s construction ensures it provides good electrical strength. Specific breakdown voltage ratings vary depending on overall thickness and are summarised in the table below:
Thickness | Designation | Breakdown Voltage |
---|---|---|
0.15mm | 2-2-2 | ?6 kV |
0.23mm | 3-3-3 | ?7 kV |
0.3mm | 3-5-3 | ?10 kV |
0.38mm | 5-5-5 | ?10 kV |
In addition to its solid electrical properties, DMD is a strong yet flexible insulation paper material. It will withstand temperatures up to 155°C (Class F) and exhibits no delamination of the layers when tested at this temperature for 10 minutes. Strength ratings for various thicknesses are included below:
Thickness | Designation | Tensile Strength Length, Before Bending |
Tensile Strength Length, After Bending |
Tensile Strength Cross, BeforeBending |
Tensile Strength Cross, After Bending |
---|---|---|---|---|---|
0.15mm | 2-2-2 | ?80 N/10mm | ?80 N/10mm | ?80 N/10mm | ?70 N/10mm |
0.23mm | 3-3-3 | ?180 N/10mm | ?150 N/10mm | ?150 N/10mm | ?120 N/10mm |
0.3mm | 3-5-3 | ?240 N/10mm | ?180 N/10mm | ?170 N/10mm | ?130 N/10mm |
0.38mm | 5-5-5 | ?290 N/10mm | ?270 N/10mm | ?270 N/10mm | ?180 N/10mm |
In addition to its excellent strength, DMD is also very easy to work with. The fleece layers on either side of the poly film are sealed with a light coating of varnish. This ensures that the material has a smooth surface finish and won’t catch if applied with machine taping systems.
DMD is typically used on low and medium voltage electric machines. Specific applications include:
We are pleased to offer DMD Paper by the metre in a selection of thicknesses. To buy online, follow these steps:
We cut all our DMD from rolls and will supply your order as one single, continuous length wherever possible. Maximum roll lengths do limit us here. All thicknesses have a maximum roll length of 50 metres.
If you require cut insulation parts or slit rolls of DMD Insulation, we can assist with those as well. To enquire, please do contact us. We’ll be happy to assist.

DMD Paper - Quick Reference Guide |
There’s a bit of a story to that one. The short answer, DMD stands for Dacron-Mylar-Dacron. This is what is was originally made from. Dacron Felt on both sides with a genuine DuPont® Mylar® layer of polyester film in the middle.
Since then, the product has become more common and different manufactures have begun to produce it. As this happened, the materials stayed the same but the generic versions (polyester felt, polyester film) are used. Nowadays, the name has stuck but it should probably be called PPP.
