浅析车用聚丙烯改性料的发展趋势

Analysis on Development Trends of Automotive Modified PP Compounds

近十几年中国汽车工业发展迅速,带动了车用聚丙烯蓬勃发展。目前聚丙烯是所有塑料中最轻的品种之一,具有优良的力学性能、成型性好、制品表面光泽好,但因收缩率大,很难生产一些尺寸精度较高的零部件,聚丙烯改性料则很好地弥补了这一缺陷。随着汽车轻量化的不断发展,聚丙烯改性料作为汽车行业应用最多的塑料,将扮演着越来越重要的角色。未来车用聚丙烯的主要发展方向将是长玻纤增强、"三高一低"(高流动、高模量、高抗冲、低气味)聚丙烯。

China＇s booming automobile industry in last decade has prompted rapid growth of automotive PP. As one of the lightest plastic products, PP boasts good mechanical property, mold ability and product surface gloss, but with high shrinkage rate, making it difficult to produce some parts with high dimensional precision. Modified PP compounds fill the gap perfectly. With continuous automotive lightweighting, modified PP compounds, as the plastics most applied in automobile industry, will play more and more important role. Main development orientation of automotive PP in future will be long glass fiber reinforced PP and three-high-and-one-low（high fluidity, high modulus, high impact and low odor） PP.
