Green shell paper is a kind of paper with high mechanical strength for insulating material. The thickness is 0.1~0.3 mm. Dark gray, easy to absorb moisture. Used as insulation paper in motors, electrical appliances and transformers. Green shell paper, also known as highland barley paper, is commonly known as green shell paper for cyan thin electrical insulating paperboard. It is made of wood fiber or mixed pulp with cotton fiber through a certain process. The commonly used colors of thin electrical insulating paperboard are yellow and cyan. Yellow is commonly known as yellow shell paper, and cyan is commonly known as green shell paper.

Green shell paper has good mechanical strength, high electrical strength, flat and smooth surface, and full of toughness. It is widely used as an insulating material in motors, electrical appliances, instruments and other equipment.

(1) Purpose of green shell paper: green shell paper is used as insulation material on electrical appliances and motors. For example, between the fan wing and the fan head of a household ceiling fan, use screws to fasten a layer of green shell paper; there is a layer of green shell paper between the main shaft pressing ring of the lathe and the gear box.

(2) Green shell paper specifications (mm): Common specifications are: 0.1, 0.2, 0.5, 1, 2.
