Classification according to the use of polyester film (1)-film supplier
Because the characteristics of polyester film determine its different uses. Different polyester films have different requirements for raw materials and additives, as well as processing technology, and their thickness and technical indicators are also different. In addition, only BOPET has multiple uses, so the films classified according to the use are all BOPET. Specifically, it can be divided into the following categories: 1. PET electrical insulation film is specially used for electronic and electrical insulation materials because of its good electrical, mechanical, thermal and chemical inertness, good insulation performance, and high breakdown voltage. Commonly used standard thicknesses are: 25μm, 36μm, 40μm, 48μm, 50μm, 70μm, 75μm, 80μm, 100μm and 125μm. Including wire and cable insulation film (thickness 25-75μm) and touch switch insulation film (50-75μm). 2. The PET capacitor film has the characteristics of high tensile strength, high dielectric constant, low loss factor, good thickness uniformity, good electrical properties, and high resistance. It has been widely used in capacitor dielectrics and insulating interlayers. Commonly used standard thicknesses are 3.5μm, 3.8μm, 4μm, 4.3μm, 4.8μm, 5μm, 6μm, 8μm, 9μm, 9.8μm, 10μm, 12μm, etc. 3. PET card protection film has good transparency, high stiffness, good thermal stability, smooth surface, excellent winding performance, uniform vertical and horizontal stretching performance, and has excellent properties such as waterproof, oil and chemical resistance. It is specially used for the protective packaging of pictures, certificates, documents and office supplies, making it smooth and beautiful after being hot stamped as a protective film, and can keep the originals clear and undeformed. Commonly used standard thicknesses are 10.75μm, 12μm, 15μm, 25μm, 28μm, 30μm, 36μm, 45μm, 55μm, 65μm, 70μm, etc., of which 15μm and above are mainly used as laser anti-counterfeiting base film or high-end card protection film.
