Explain the grade classification of pet film for you-film supplier
1. Polyimide film: It has excellent physical and electrical properties in a wide temperature range, high heat resistance; excellent radiation resistance and corona resistance. Used in wire and cable wrapping insulation, high-temperature motor coil insulation and slot insulation, printed circuits and cables; 2. Polypropylene film: rich in raw materials, low in price, biaxially stretched polypropylene film is better than cast and blown polypropylene film High and uniform mechanical strength; low elongation and shrinkage; high and uniform electrical strength, widely used in power capacitors, cables, electrical appliances; 3. Polycarbonate film: mechanical properties, electrical breakdown performance and dielectric loss tangent are uniform Second to polyester film, but its size is stable, temperature has little effect on its electrical properties, water absorption is small, cold resistance is good, and it can be metalized. However, it will be slowly corroded by amines and alkalis, and can be partially soluble in aromatic hydrocarbons, ketones and esters. It is used to insulate motor coils, slots, conductors, speakers, phones, etc.; it is a professional manufacturer of PET film with multiple functions, such as: transparent PET film, milky white PET film, release PET film, and supply PET motor film.
