The use of DMD insulating paper materials are: the mutual insulation of the components of the electrical network requires a relatively small relative dielectric constant. The dielectric of the capacitor requires a large relative dielectric constant, and both require a small dielectric tangent, especially for insulating materials applied at high frequencies and high voltages. To minimize dielectric loss, insulation materials with dielectric loss tangent are required. DMD insulation paper has the following characteristics: chemically resistant, shiny, partially transparent or translucent, mostly good insulators, light weight and strong, easy to process, mass-produced, inexpensive, versatile, useful, easy to color, partially resistant to high temperatures.

After the processed DMD insulation paper has passed the inspection, the staff will carefully package the customer’s goods, making sure the goods are delivered to the customer’s hands neatly and in good condition. DMD insulating paper is a kind of insulating material processed according to the above steps. It is a composite insulating material made of polyester film coated with grade F adhesive and polyester fiber non-woven fabric on one side. DMD electrical insulation paper has good mechanical strength, dielectric properties and high heat resistance. It is Y series of motor insulation materials that can be used as slot insulation, inter-turn and inter-layer insulation, gasket insulation and transformer insulation for small and medium-sized motors.

In the use of insulating paper in electrical products, material evaluation has two purposes: one is the evaluation of a material that is part of an electrical insulation structure, and the other is the evaluation of a material that is used alone or as a simple composite part of insulating structures. Many insulating papers of a generic type can be very different in heat resistance. Therefore, it is not appropriate to judge their heat resistance according to the chemical name of the genus of the insulating paper. Insulating papers used in the insulation structure of electrical products, their respective heat resistance may be affected by other materials. In addition, the heat resistance of various materials depends to a large extent on the specific functions they assume in the insulating structure.

DMD insulation paper is a composite insulating material made of a polyester film coated with a F-grade adhesive and a polyester fiber non-woven fabric on one side, referred to as DMD. Fish paper is a fluoroplastic processed paper product. The surface color of fish paper is lividity, with strong tensile strength, longitudinal and transverse bending. Its temperature resistance is 130°C, withstand voltage of 4000 volts, no foaming, no glue, suitable for insulation protection of electrical appliances, enameled wire, transformer. Features of fish paper: Good insulation, flexibility, water  resistance, wear resistance, grease resistance, aging resistance, good gap blocking material.

Insulation materials are mostly used in different types due to physical properties, temperature, humidity, chemical resistance, etc. Insulation paper is one of them; insulating paper can be used according to the thickness of the insulation, and the actual required length can be adjusted by the staff. Under the premise of the original insulating paper, the insulating paper tape is cut into various widths, which can effectively control the cost, save time and improve efficiency, and reduce many troubles. The insulating paper tape can also be guaranteed the performance of its insulating medium, gray damage and so on due to the clean and tidy processing environment of our company.
