目前,己工业化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19(含聚砜和聚醚砜)、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、聚硫醚酮、聚硫醚醚酮等)。特种工程塑料的发展历史至今不足40年,但因其性能优异,发展速度很快,已成为机械、电子、汽车、航空、航天和尖端技术不可缺少的选用材料。然而因其价格昂贵(如日本市场的PEEK价格比聚丙烯高99倍以上,为通用工程塑料的23-33倍;聚醚砜为聚丙烯
At present, there are many types of special engineering plastics that have been industrially produced. Its main varieties are polyarylates, polyphenyl esters, poly 19 (including polysulfone and polyether sulfone), polyphenylene sulfide, and polyimide (including polyether acyl Imines, polyamideimides, etc.), liquid crystal polymers, and polyaryletherketones (including polyether ketones, polythioether ketones, polythioether ether ketones, etc.). The history of development of special engineering plastics has been less than 40 years, but due to its excellent performance and rapid development, it has become an indispensable material for machinery, electronics, automobiles, aviation, aerospace and cutting-edge technologies. However, due to its high price (such as the Japanese market PEEK price is more than 99 times higher than polypropylene, 23-33 times that of general engineering plastics; polyether sulfone is polypropylene
