随着我国汽车工业和电子工业的快速发展有效地拉动了工程塑料产业的发展。据介绍,2012年国内工程塑料消费量为294.5万吨,同比增长7.6%,是全球需求增长最快的国家。预计今后10年内的需求量,将以8%~11%的速度增长。作为1,4-丁二醇(BDO)的第二大消费领域,PBT树脂是工程塑料的重要品种。截止2011年世界有30多家PBT树脂生产企业,总产能约130万吨/年。其中,中国占世界总产能的25%,约为42万吨/年。然而,由于众多原因,我国PBT树脂用量虽然在逐年上升,树脂开工率却依然不高,在70%下方徘徊。
With the rapid development of China’s automobile industry and electronics industry, it has effectively stimulated the development of engineering plastics industry. According to reports, in 2012 the domestic consumption of engineering plastics 294.5 million tons, an increase of 7.6%, is the fastest growing global demand for the country. It is estimated that the demand in the next 10 years will increase by 8% ~ 11%. As the second largest consumer of 1,4-butanediol (BDO), PBT resin is an important engineering plastic. As of 2011, there are more than 30 PBT resin manufacturers in the world, with a total capacity of 1.3 million tons / year. Among them, China accounted for 25% of the world’s total production capacity, about 420,000 tons / year. However, due to many reasons, although the amount of PBT resin in our country is increasing year by year, the operating rate of resin is still not high, hovering below 70%.
