精对苯二甲酸(PTA)主要用于生产聚酯,而聚酯纤维是合成纤维中最主要的品种,国内聚酯纤维在合成纤维总产量中超过80%。近年来,非纤领域聚酯的用量持续增长,包括瓶级聚酯和聚酯薄膜,已经广泛用于各种饮料的包装、胶片、光盘等领域,消费量呈逐年上升的趋势。另外PBT、PTT等新型聚酯产品随着工业应用的普及,消费量大幅增加。新兴市场为PTA产业的发展提供了广阔空间。但是,国内PTA产能迅猛扩张,已经逐渐呈供过于求的局面,而且短期内尚无向好迹
Polyester terephthalate (PTA) is mainly used to produce polyester, while polyester fiber is the most important type of synthetic fiber. Domestic polyester fiber accounts for more than 80% of the total output of synthetic fiber. In recent years, non-fiber polyester area continued growth in the amount of use, including bottle-grade polyester and polyester film, has been widely used in various beverage packaging, film, CD and other fields, consumption showed a trend of increasing year by year. In addition PBT, PTT and other new polyester products with the popularity of industrial applications, consumption increased significantly. Emerging markets provide ample space for the development of the PTA industry. However, the rapid expansion of domestic PTA capacity has gradually presented an oversupply situation, and there is no sign of good track in the short term
