近10年来世界聚酯(PBT,PET)需求量逐年上升,1990年为150万t,到2000年增长了近5倍,达到700万t/a。据统计,1990～1994年聚酯总生产能力年均增长14％,而1995～1999年年增长率跃增到21％。其中,1995～1999年,亚洲的聚酯年生产能力由100万t猛增到300万t。同时,近10年中聚酯生产商的数量也翻了一番,1990,1995和2000年分别为35家、50家和75家。其中亚太地区占聚酯总生产能力的
In the past 10 years, the demand for polyester (PBT, PET) in the world has increased year by year. In 1990, it was 1.5 million tons. By the year 2000, it has increased nearly 5 times to 7 million t/a. According to statistics, the average annual growth rate of polyester production from 1990 to 1994 was 14%, and the annual growth rate from 1995 to 1999 jumped to 21%. Among them, from 1995 to 1999, the annual production capacity of polyester in Asia soared from 1 million tons to 3 million tons. At the same time, the number of polyester manufacturers has doubled in the last 10 years. In 1990, 1995 and 2000, they were 35, 50 and 75 respectively. The Asia-Pacific region accounts for the total production capacity of polyester
