Mylar® electro insulating films made of PETP

Composition of Mylar A:

Mylar® A is manufactured of polyethylene terephthalate (PETP) and belongs to the area of insulating materials of the insolation class B (up to 130°C).

Properties of Mylar A:

The polyester film Mylar® A is resistant against tensile and tears and it has excellent electrical properties. This material is well-resistant against heat, cold and common solvents.

Mylar® A is UL certificated (UL-File E93687). Since the Dr D. Mueller GmbH is a UL recognized repackager, the materials do not lose their UL certification during processing.

Applications for Mylar A:

Mylar® A is used as intermediate- and cover insulation in transformers, chokes and relay coils.

Furthermore it is used as slot- and phase insulation, as slot closure und slot casing in the electro machine-, generator- and magnet construction as well as insulating layer in electrical devices.

Moreover Mylar A is used as stencil material. In this case the outlines are mostly laser-cut.

Storage requirements
Mylar® A is storable unlimited under normal conditions (20°C, 50% relevant humidity).

Adhesive Tapes made of Mylar A

Adhesive tapes can be made of the different thicknesses. Therefore Mylar A polyester film is covered with different adhesion systems. Generally Mylar A is covered with acrylate adhesives, but we also provide silicon adhesive covers for special applications.

Washers made of Mylar

We manufacture numerous washer gaskets for different application areas for the industry of this polyester film Mylar A.

The material can be used in many applications because of the good heat- and cold resistance.

We deliver the following measurements: M3 M4 M5 M6 M8 M10

Other measurements can also be manufactured.

Wound pipes made of Mylar A

We wind pipes out of this polyester film Mylar A which can be used as insulating for pins or connections.

These insulating casings can be manufactured in different diameters.
