6520 Fish Paper

Type:Insulation Paper
Material:polyester film+ barley paper
Tensile Strength:≥500MPa


Insulation Fish Paper Polyester Film Paper Product Features:

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.

Usage of 6250 fish paper:

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.
