世界聚丙烯工业的发展趋势

Development Trend of World Polypropylene Industry

聚丙烯工业产能不断扩大,兼并、联合、重组事件不断。2001年全球PP生产能力达到36Mt/a,预计2005年将达到48Mt/a。2001年我国PP的产量达到3.225Mt,预计2005年生产能力将达到4.1Mt/a。近年来,聚丙烯的催化剂技术也不断改进,茂金属和单活性中心催化剂技术使PP产品性能显著改善。

The capacity of polypropylene ( PP) has continuously increased, and the merge, combination, and reconstruction among the enterprises have ceaselessly occurred. The global capacity of PP reached 36 Mt/a in 2001 , and will reach 48 Mt/a in 2005. In our country, the production of PP reached 3. 225 Mt in 2001, and the predicted capacity of PP will reach 4. 1 Mt/a in 2005. In recent years, the catalyst technologies using for PP production have developed quickly. The metallocene and single - site catalysts have made the product properties of PP obviously improved.
