当前,已工业生产的特种工程塑料品种很多,其主要品种为聚芳酯、聚苯酯、聚砜(含聚芳砜和聚醚砜)、聚苯硫醚、聚酰亚胺(含聚醚酰亚胺和聚酰胺酰亚胺等)、液晶聚合物和聚芳醚酮(含聚醚酮、聚醚醚酮、聚硫醚酮、聚硫醚醚酮)等特种工程塑料的发展历史至今不足40a,但因其性能优异,发展速度很快,已成为机械、电子、汽车、航空、航天和尖端技
At present, there are many types of special engineering plastics that have been industrially produced. Its main varieties are polyarylates, polyphenylesters, polysulfones (including polyarylsulfone and polyethersulfone), polyphenylene sulfide, and polyimides (including polyethers). The history of the development of specialty engineering plastics such as imides and polyamide imides, liquid crystal polymers, and polyaryletherketones (including polyether ketones, polyether ether ketones, polythioether ketones, and polythioether ether ketones) Less than 40 years, but because of its excellent performance and rapid development, it has become a mechanical, electronic, automotive, aerospace, aerospace and advanced technology.
