6021 Milky Polyester Film/Mylar
Description
6021 Milky white polyester film is biaxially oriented polyethelene terephthalate (PET) film
Features
· Dimensional stability
· Thermal stability at elevated temperatures
· Coefficient of friction
· Tensile break strength
· Tensile yield strength
· Elongation at break
· Chemical and electrical resistance
· High dielectric constant
· Lower extractable content
· High electrical breakdown voltage
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.
Available
In rolls, in strips
