1.High mechanical and tensile strength; Easily bendable and perforated without any cracking; Exceptionally light weight, about half the weight of aluminum.
2.Excellent electrical properties, ideal arc resistance, tear resistance; Possesses the beneficial properties of metals, plastics, rubber and leather; Environment friendly, poses no threat to nature, easily disposable.
Green shell paper is used for electrical insulation materials 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.
And it is also used to make 6250 polyester film composite foil.
Executive standard: JB/T4059-1991
