Thick polyester film

Thick polyester film (more than 50 microns) is commonly utilized as a reliable insulation material for various motor applications, including ground and phase insulation. In addition, these films are also available in milky white and hazy variants, making them highly versatile for numerous applications across various industries, such as electronics, heat transfer, injection printing, blistering, screen printing, offset printing, and flexo printing.

Milky White Thick Films: These films are known for their exceptional mechanical and dielectric properties, making them a popular choice for various electrical insulation applications. They are commonly used as interturn and liner insulation, as well as wrapping insulation for coils and cables and slot insulation in rotating electrical machines. With their excellent insulation properties, Milky White Polyester films are an ideal choice for applications where high performance and reliability are crucial.
