由于对易加工树脂的需求,发展中地区对低密度聚乙烯(1dPE)的潜在增长起着关键作用。亚洲是全球需求增长最快的地区,增长率达5.7%/a。供需情况APME的数据显示,西欧1dPE去年的产量比1998年的482万t略有下降,为479万t。该产品的市场缓慢增长了数年,虽然在90年代后半期增长有明显加速,但总的说来增长率约为1.5%～2.0%/a。1dPE增长率低的主要原因是线性低密度聚乙烯(11dPE)在许多终端应用中取得了进展。据报道,2000年对1dPE的需求如此强劲,以致在某些情况下乙烯原料供不应求。自从DSM公司1993年建立了生产能力为20万t/a的工厂以来,欧洲几乎没有增加新的生产能力。但是,Elenac公司正在 Due to the demand for easy-to-process resins, developing regions play a key role in the potential growth of low density polyethylene (1dPE). Asia is the region with the fastest growth in global demand, with a growth rate of 5.7%/a. Supply and demand data from APME shows that the output of Western European 1dPE last year decreased slightly from 4.82 million tons in 1998 to 4.79 million tons. The market for this product has been growing slowly for several years. Although there has been a marked acceleration in growth in the second half of the 1990s, the overall growth rate is about 1.5% to 2.0%/a. The main reason for the low growth rate of 1dPE is that linear low density polyethylene (11dPE) has made progress in many end applications. According to reports, the demand for 1dPE in 2000 was so strong that in some cases the supply of ethylene was in short supply. Since DSM established a factory with a production capacity of 200,000 t/a in 1993, there has been little increase in new production capacity in Europe. However, Elenac is
