Introduction to the function and use of polyester film

Polyester film is an essential raw and auxiliary material for LCD products. For example, the protective film, release film, reflective film, diffusion film and brightness enhancement film and other backlight substrates are all high value-added special functional polyester film products. This type of polyester film has excellent electrical insulation properties. No defects, high light transmittance, and good coating processing performance. Polyester films with excellent mechanical properties, heat resistance, electrical insulation properties, water vapor barrier properties, dimensional stability, tear resistance, weather resistance, and good coating processing properties are being developed and used in the solar photovoltaic industry. , Such as the main material of products such as solar TPT backing material; architectural glass film with polyester film as the base material can transform cheap ordinary transparent flat glass into safe and heat-insulating glass with multiple colors and multiple functions. Its main functions are heat insulation and energy saving, UV protection, explosion and shock resistance, privacy protection, decoration and light transmission. This kind of polyester film has the characteristics of high transparency, high cleanliness, good flatness, and good coating processing performance.
