Product Description

Product Description

6021 PET polyester film or mylar electrical insulation sheets, or mylar polyester film is made of PET molten and biaxial directional drawing. The 6021 polyester film has good insulation performance and excellent mechanical properties. It is a widely used electrical insulation film and can be used to produce soft composite material, wire wrap, electronic electrical insulation gasket, motor groove, inter-turn insulation, and print, etc.

 

Product Parameters

Type: Insulation Film
Insulation class: E (120°C)
Thickness: 0.125-0.35mm
Width: 1000mm or customized
Form: in rolls
Color: milky white
 

Our Advantages

1. Low coefficient of friction
2. Excellent lamination
3. Good shape retention and spring effect
4. High dielectric strength.

 

Applications

It can be used as an electrical insulation and as a laminate with other substrates.
In motor applications, selected types of polyester film can be used for ground insulation as slot liners and wedges, as well as phase insulation. In wire and cable applications, it is ideal for mechanical barriers.
In addition, specialized polyester film can be used in transformer and high-voltage distribution equipment to wrap the conductors. They are effective for use in hermetic applications with refrigerator and air conditioner motor / compressor assemblies.

It can also be used in packaging, glass steel, clothing collar lining and other occasions.
