VPV / DMD - Laminates
Structure of VPV/DMD laminates
VPV/DMD laminates are flexible 3-layer insulations made of polyester film (Mylar, Hostaphan etc.) coated on both sides with impregnated polyester fleece.
Properties of VPV/DMD laminates
DMD laminates have high dielectric strength and high mechanical stability.
Processing of VPV/DMD laminates
The smoothness of the material ensures excellent machinability.
- Insulation class F (up to 155°C)
- flexible 3-layer insulation made of polyester film
- with impregnated fleece layer on both sides
- high dielectric strength
- high mechanical stability
- the smooth surface enables good machine workability
- good adhesion behaviour in combination with impregnating resins

Dr. Müller as your contact for DMD parts
When it comes to DMD, we are the right contact. You can buy DMD from us in rolls, sheets or machined parts.
We stock DMD in various thicknesses. We have DMD sheets up to a thickness of 1.4 mm in stock. We also have rolls in stock from a thickness of 0.09 mm.
Adhesive tapes made of DMD
DMD is also supplied in self-adhesive form, e.g. as adhesive tapes. These can be equipped with various adhesive systems.
DMD in the form of stamped parts
DMD is processed in large quantities into insulating parts, seals and washers using the stamping manufacturing process.
Laser processing of DMD
Laser processing of DMD can be carried out with either a 10.6 µm or a 9.3 µm CO2 laser.
Laser cutting of DMD with a CO2 laser produces a clean cut with minimal discolouration.
Laser marking of insulating paper with a CO2 laser produces a non-removable surface mark with no depth, which can be either lighter or darker depending on the material being processed.
Laser engraving of DMD produces both depth and contrast, depending on the material being machined, and is limited to the thickness of the material.

You can download data sheets for the material DMD by clicking on the PDF symbols. Here you can see the characteristics of the material, such as the temperature resistance or the chemical resistance as well as the dielectric strength.
Application advice for DMD
If you need data on DMD that you cannot find in the data sheets, our application technology department will be happy to advise you. We can also advise you on the manufacture of stamped parts made of DMD, moulded parts made of DMD and cover slides made of DMD.
