Fish Paper Polyester Film Laminate 6520

This is fish paper with polyester film, electrical insulation is a flexible composite insulation material made by laminating electrical-grade presspaper with polyester film (PET/Mylar). It is commonly used as electrical fish insulation paper for slot insulation, phase insulation, liner insulation and general fish paper for insulation in motors, transformers, coils and other electrical equipment.

What Is Composite Electrical Insulation Paper?

This is a two-layer composite insulation material designed for electrical applications that require both dielectric insulation and mechanical strength.

It is produced by laminating:

• one layer of electrical-grade presspaper

• one layer of polyester film (PET/Mylar)

This structure combines the advantages of both materials and creates a flexible but durable insulation sheet that can be cut, punched and formed into different electrical insulation parts.

In practical use, fish paper is selected when plain insulation paper is not enough and a more stable composite insulation material is needed.

The composite insulation Paper, commonly known as Fish Paper with film or Laminated Barley paper, is a two-layer composite material engineered for demanding electrical applications. It is manufactured through a precise and controlled lamination process. In this process, a layer of electrical-grade presspaper is permanently bonded to a layer of polyester film (also known as PET or Mylar). 

Properties & Advantages of PET Laminated Fish Paper:

○Excellent Dielectric Strength: The polyester film layer provides superior electrical insulation.

○High Mechanical Strength: The presspaper base offers great puncture and tear resistance.

○Good Flexibility: Easy to handle, cut, and form for complex shapes.

○Impregnation Friendly: Allows varnishes and resins to penetrate for a solid insulation system.
