  • Available in a selection of thicknesses by the roll, linear metre or a custom cut tapes and parts.

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:

Excellent Electrical Insulation Properties.

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

Good Mechanical Strength.

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:

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.

Applications for DMD Insulation Paper.

DMD is typically used on low and medium voltage electric machines. Specific applications include:

  • Slot liner for electric motors.
  • Phase insulation.
  • Interlayer insulation material for transformers.
