Application of polyimide film

Used as insulating varnish for magnet wire, or as high temperature resistant paint.

Advanced composite materials: used in aerospace, aircraft and rocket components, is one of the high temperature resistant structural materials. For example, the supersonic airliner plan 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 carbon fiber with thermoplastic polyimide as the matrix resin. Reinforced composite materials, the amount of each aircraft is about 30t.

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.

Foamed plastic: used as heat-resistant and heat-insulating material.

Engineering plastics: There are thermosets and thermoplastics. Thermoplastics 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.

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.

The above is the application of polyimide film in film, which can help to further understand polyimide film.
