Thick 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.

Characteristics

Mechanical Strength: The increased thickness of these films results in higher mechanical strength and stiffness, making them suitable for applications requiring durability and dimensional stability.
Thermal Stability: Thick polyester films exhibit good thermal stability, allowing them to withstand high temperatures during processing and use without deforming or degrading.
Electrical Insulation: Due to their high dielectric strength and excellent electrical insulation properties, thick polyester films are widely used in electrical and electronic applications such as capacitor manufacturing, cable insulation, and electrical insulation tapes.

4. Barrier Properties: Depending on their thickness and composition, thick polyester films can offer barrier properties against moisture, gases, and odors, making them suitable for packaging applications where protection from external elements is necessary.
5.Printability: Thick polyester films can be easily printed using various printing techniques, making them suitable for applications requiring high-quality graphics and branding, such as signage, banners, and displays.
6. Laminating: These films can be laminated with other materials to enhance their properties, such as adding barrier coatings or adhesives for specific applications.
