Want to know what are the applications of polyimide film? Look at these

Polyimide film is one of the early products of polyimide, used for slot insulation of motors and cable wrapping materials. The main products are DuPont Kapton, Ube Industries’ Upilex series and Zhongyuan Apical.

The transparent polyimide film can be used as a flexible solar cell base plate. IKAROS sails are made of polyimide films and fibers. Polyimide fibers can be used to filter hot gases, and polyimide yarns can separate dust and special chemicals from exhaust gas.

1. Paint: Used as insulating paint for magnet wire, or as high temperature resistant paint.

2. Advanced composite materials: used in aerospace, aircraft and rocket components. It is one of the high temperature resistant structural materials. For example, the US’s supersonic passenger aircraft program designed a speed of 2.4M, a surface temperature of 177°C during flight, and a required service life of 60,000 hours. According to reports, 50% of the structural materials have been determined to be based on thermoplastic polyimide resin. The amount of carbon fiber reinforced composite materials for each aircraft is about 30t.

3. Fiber: The modulus of elasticity is second only to carbon fiber. It is used as a filter material for high-temperature media and radioactive materials and bulletproof and fireproof fabrics. Various polyimide products are produced in Changchun, China.

4, foam plastic: used as high temperature heat insulation material.

5. Engineering plastics: There are thermosetting and thermoplastic types. Thermoplastic types can be compression molded or injection molded or transfer molded. Mainly used for self-lubricating, sealing, insulating and structural materials. Guangcheng polyimide materials have begun to be applied to mechanical parts such as compressor rotors, piston rings and special pump seals.

6. ​​Separation membrane: Used for the separation of various gas pairs, such as hydrogen/nitrogen, nitrogen/oxygen, carbon dioxide/nitrogen or methane, to remove moisture from air hydrocarbon feed gas and alcohols. It can also be used as pervaporation membrane and ultrafiltration membrane. Due to its heat resistance and resistance to organic solvents, polyimide is of special importance in the separation of organic gases and liquids.
