Description
Polyester film insulating paper soft composite material (commonly known as green shell composite paper) is a two-layer composite material made of electrical insulating paper and polyester film bonded by adhesive. It has good dielectric properties and high mechanical strength. Suitable for slot liners and turn-to-turn insulation in electric motors and appliances.
Fish paper is a two-layer flexible composite material, produced by B Class adhesive to adhere insulation paper with polyester film together
--Two layers: polyester film is bonded with insulating paper.
--Base Layer: 100% Sulfate wood pulp presspaper
--Outer Layer: Polyester film(PET) for Electrical Purposes
Advantages of the Fish Paper:
—Outstanding dielectric properties
—Fish paper electrical insulation has good mechanical strength because it’s fibrous
—Retains greater flexibility than plastics at low temperatures
Features of the Fish Paper:
—Width: 10-1300mm
—Thickness: 0.08-0.45mm
--Form: roll, sheet, strip
--Colur: Blue, cyan, nature brown. Special colours can be provided on request. --Three or four layers can be produced on request.
--The insulation system has been approved by UL (NO.: E310670) and the products have passed ROHS and RECH test.
