Polyimide Film Product
Polyimide film is one of the earliest polyimide products used in motor slot insulation and cable wrapping materials.
Paint: Used as insulating paint for magnet wire, or as a high temperature paint.
Polyimide film Applications
1.Advanced composite materials: for aerospace, aircraft and rocket components. Is one of the most high temperature structural materials. For example, the United States plans for the supersonic airliner designed speed of 2.4M, flight surface temperature of 177 ℃, life expectancy of 60000h, it has been reported that 50% of the structural material has been identified as thermoplastic polyimide matrix resin Of carbon fiber reinforced composites, the amount of each aircraft is about 30t.
2.Fiber: Elastic modulus second only to carbon fiber, as a high temperature medium and radioactive material filter material and bullet-proof, fire-resistant fabric. Changchun, China have a variety of polyimide products.
3.Foam: used as a high temperature insulation material.
4.Engineering Plastics: There are thermosetting thermoplastic, thermoplastic molding can also be used injection molding or transfer molding. Mainly used for self-lubricating, sealing, insulation and structural materials. Polyimide materials have begun to be used in compressor rotary vanes, piston rings and special pump seals and other mechanical components.
5.Separation Membrane: for the separation of various gas pairs, such as hydrogen / nitrogen, nitrogen / oxygen, carbon dioxide / nitrogen or methane, etc., to remove moisture from air hydrocarbon feedstock and alcohols. Can also be used as pervaporation membrane and ultrafiltration membrane. Due to the polyimide’s resistance to heat and organic solvents, it is of particular importance in the separation of organic gases and liquids.
