Abstract
In this paper, the density, melt flow rate, impact strength, and shrinkage of four kinds of polypropylene resins used in injection molded appliances were tested, and their crystallization behavior and crystal structure were characterized using polarizing microscope. The affecting factors on impact strength and processing performance of EP548R were analyzed. When nucleating agents were added, the mechanical properties of EP548R increased, and met the demands for large injection molded thin-walled products.关键词
