Description of Fish Paper
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
Electrical Properties: Fish paper possesses outstanding dielectric properties and good arc resistance, making it an ideal electrical insulator for applications like motor windings and transformers.
Mechanical Properties: Due to its fibrous nature, fish paper has high mechanical strength, is wear-resistant, and offers good tear resistance.
Temperature Resistance: It maintains its strength and flexibility at low temperatures better than plastics and is more heat-resistant than many comparable plastic materials.
Fabrication: Fish paper is easy to punch, die-cut, and form into various shapes, making it a versatile material for diverse applications.
Lightweight: It is a lightweight material, weighing about half as much as aluminum, which is beneficial for weight-sensitive applications.
Fire Resistance: Fish paper exhibits high fire resistance, capable of slowing combustion and reducing flame spread.
Flexibility: Despite its high strength, fish paper remains highly flexible, especially at low temperatures, making it more resilient than many plastics.
Chemical Resistance: It is insoluble in common solvents like petroleum, alcohol, and turpentine.
