β成核剂改性聚丙烯研究进展

Research Progress of β-nucleating Agent Modified Polypropylene

聚丙烯问世以来,以出色的热性能和力学性能在很多领域,如注塑、薄膜、纤维生产中得到广泛的应用,这种通用性和经济性使聚丙烯超过了聚氯乙烯、聚苯乙烯,成为仅次于聚乙烯的第二大合成树脂。

Since the advent ofpolypropylene, with excellent thermal and mechanical properties in many fields, such as injection molding, film, widely used in the production of fiber, the versatility and economy make polypropylene than PVC, polystyrene, become the second largest synthetic resin after polyethylene.
