聚丙烯改性技术及制品应用

POLYPROPYLENE MODIFICATION TECHNOLOGY AND PRODUCT APPLICATION

介绍了我国聚丙烯质轻、耐腐蚀、易加工、力学均衡性好、价廉,但低温脆性大和成型收缩率大的特点及其发展现状和改性技术,列举一些改性技术实例,说明经过改性后显著提高其性能,大大拓宽其应用范围。

The characteristics of China-made polypropylene, such as light weight, corrosion resistance, easy processing, good balance in mechanical properties and low cost on one side but brittleness at low temperature and high molding shrinkage on the other, are introduced. Its current developments and modification technology are presented. Modification examples are cited to demonstrate that modified polypropylene has much improved properties and largely expanded applications.
