Polyimide film is a new type of high temperature resistant organic polymer film, which is formed by condensation polymerization of pyromellitic dianhydride (PMDA) and diaminodiphenyl ether (ODA) in a strong solvent dimethyl acetamide (DMAC), salivation to form a film, and then amination. It is a film type insulating material with good performance in the world at present, and has excellent mechanical properties, electrical properties, chemical stability and high radiation resistance High and low temperature resistance (-269 ℃ to+400 ℃).
1. Performance and advantages: The polyimide film can be used for a long time in the temperature range of - 269 ℃ - 400 ℃. Within this temperature range, it has excellent physical properties, electrical insulation properties, flame retardancy, mechanical properties, and excellent resistance to high and low temperatures, radiation, and chemical stability. Accurate size, flatness, and uniform thickness.
2. Product Usage: It can be used as an insulation layer material for high-temperature heating products, such as electric heaters, high-temperature resistant printed circuit substrates, insulation layers for wires and cables, electromagnetic wires, and insulation materials for various motors. Widely used in aerospace, electric motors, lighting fixtures, audio equipment, transformers, instrument communication, petrochemical industry, etc.
Corona resistant polyimide (PI) film is a heterocyclic polymer material characterized by ring structure. It has excellent mechanical properties, electrical properties, heat resistance and radiation resistance at 200~400 ℃. It is a kind of insulation material with excellent comprehensive performance. With the rapid development of various technological fields such as aviation, rail transit, and electronic information, as well as the continuous segmentation of markets and products, as well as the exploration of emerging research fields, traditional methods can no longer meet the diversified needs of the market. Therefore, domestic and foreign researchers have made certain progress in preparing PI membranes with special functions through special monomers, and modifying traditional PI membranes by adding functional nano fillers to meet the performance requirements of PI membranes in different fields.
However, in recent years, the price of polyimide film has also risen due to the substantial increase in raw materials. Choose polyimide film, Xuchang Eric Insulating Products Co., Ltd. will give you a good price and service! Big brand, trustworthy!
