近年来全球茂金属聚乙烯需求剧增,据预测,到2005年,mPE需求的年均增长率为25%,总量可望达到300多万吨。其中,茂金属线型低密度聚乙烯(mLLDPE)约占线型低密度聚乙烯(LLDPE)总消费量(1,300万吨/年)的15%,预计5年内将达到20%。今後5年内,mLLDPE的年增长率将高於LLDPE,达到25%。许多发达国家纷纷采用mLLDPE替代常规的LLDPE,如2006年日本的mLLDPE消费量预计年增长率为10%。茂金属高密度聚乙烯(mHDPE)目前的消费量为15万吨/年,到2006年,mHDPE年增长率为30%,超过200万吨。5年内,mHDPE将占HDPE总量的5%,新的mHDPE产品将持续推出。
In recent years, global demand for metallocene polyethylene has risen sharply. It is predicted that the average annual growth rate of mPE demand will reach 25% by 2005, with the total expected to reach over 3 million tons. Among them, metallocene linear low density polyethylene (mLLDPE) accounts for about 15% of the total consumption of linear low density polyethylene (LLDPE) (13 million tons / year) and is expected to reach 20% in five years. In the next five years, the annual growth rate of mLLDPE will be higher than that of LLDPE, reaching 25%. Many developed countries have adopted mLLDPE instead of conventional LLDPE. For example, the estimated annual growth rate of mLLDPE consumption in Japan in 2006 is 10%. The current consumption of metallocene HDPE (mHDPE) is 150,000 tons / year. By 2006, the annual growth rate of mHDPE is 30%, exceeding 2 million tons. In five years, mHDPE will account for 5% of the total HDPE, the new mHDPE products will continue to launch.
