4,4′-Oxydianiline
Specifications
| 4,4′-diamino diphenyl ether(4,4′-Oxydianiline) is a very important polymer monomer. Polyimide resin, poly maleimide resin, and polyamide-imide resin are all synthesized from it. These products have the advantages of excellent high-temperature resistance, low-temperature resistance, high strength, and high modulus, high creep resistance, high dimensional stability, low coefficient of thermal expansion, high electrical insulation, low dielectric constant and low loss, radiation resistance, corrosion resistance, etc., can be made into polyimide (PI) films, high-temperature resistant engineering plastics, matrix resins for composite materials, high-temperature resistant adhesives, fibers and foams, and other material forms, widely used in aerospace, electrical insulation, liquid crystal display, automobiles, medical, atomic energy, satellites, nuclear submarines, microelectronics, precision machinery packaging and other fields. |
