engineering plasticsis inAlthough nylon 66 resin was successfully developed and put into production as early as 1939, it was mainly used to make synthetic fibers until the 1950 s.engineering plasticsThe rapid development of polyacetal and polycarbonate was successfully developed in the late 1950 s. Due to the high crystallinity of polyoxymethylene, it has excellent mechanical properties, which makes plastic a material that can replace metal and ranks among the ranks of structural materials. Later, with the successful development of co-formaldehyde and the popularity of screw injection molding machines, the important position of engineering plastics in the field of materials was further established. Polycarbonate is a kind of transparent engineering plastics with excellent comprehensive performance. It is widely used and is one of the engineering plastics with rapid development. Inengineering plasticsfield, its output and consumption is second only to polyamide.

In 1961, DuPont successfully developed polyimide, which opened the way for the development of special engineering plastics. The emergence of polyimide has also promoted the development of many heat-resistant engineering plastics, such as polysulfone, polyphenylene sulfide and polybenzimidazole, and has a profound impact on the development of the plastics industry.

American General Company inIn 1964, the polyphenylene ether resin developed by it was put into industrial production.

In 1980, the British company ICI successfully developed a specialengineering plasticsPolyetheretherketone (PEEK), which has a melting point of up to 336°C. PEEK has excellent heat resistance, radiation resistance and chemical resistance, and can be injection molded, which has attracted wide attention. Composite materials based on PEEK and reinforced by glass fiber or carbon fiber have been used in the aerospace field.

InThe successful development of thermotropic liquid crystalline polymers in the mid-1980s was another major event in the history of special engineering plastics. Liquid crystal polymer has excellent heat resistance, the use temperature can reach more than 200 ℃, has the advantages of self-reinforcement, high strength, high modulus, chemical resistance, low melt viscosity, convenient molding, and has a very wide range of applications in the field of electronics.
