Insulation paper composites manufacturers introduce organic solid insulation materials for you

Organic solid insulation materials are a class of solid insulation insulation materials. The solid insulating material is used to isolate the solids of different potential conductors, and also has a supporting effect. Compared with gas and liquid insulation materials, it has a higher density and thus a much higher breakdown strength, which is important for reducing the insulation thickness.

        Including insulating varnish, insulating rubber, insulating paper, insulating fiber products, plastics, rubber, lacquered paint tubes and insulating impregnated fiber products, electrical films, composite products and adhesive tapes, laminates for electricians, etc.

        In the early 19th century, paper, cotton, silk, rubber, and curable vegetable oil were mainly used. These materials are flexible, can meet the application process requirements, and are easy to obtain.

        In the 20th century, artificial synthetic polymer materials were used. Bakelite was first used as an insulating material. Later, polyethylene and polystyrene appeared. Due to their low dielectric constant and dielectric loss, they met the requirements of high frequency and adapted to the development of new technologies such as radar. Silicone resin combined with less alkali glass cloth greatly improves the heat resistance level of motors and electrical appliances. Polyethylene formal is a paint-based enameled wire that opens up a broad prospect for enameled wire, replacing the wire and yarn envelope. The thickness of the polyester film is only a few tens of micrometers, and it is used to replace the original paper and cloth, so that the technical and economic indicators of the motor and the electric appliance are greatly improved. The aramid fiber paper is combined with the polyester film and the polyimide film to make the heat resistance level of the motor slot insulation F grade and H grade, respectively (see insulation heat resistance grade and heat aging test). Similar developments have been made with elastomeric materials such as heat resistant silicone rubber, oil resistant nitrile rubber, and subsequent fluoroelastomers, ethylene propylene rubber, and the like.
