DEVELOPMENT AND PRODUCTION OF TRANSPARENT POLYPROPYLENE SPECIAL MATERIAL FOR INJECTION

Sun Yumei, Sun Wei, Wu Wengu(Research Insititute of Daqing Petro-Chemical Company, Daqing 163714, China)Yang Xiaodong, Yan Xiufeng(Plastic Plant of Daqing Petro-Chemical Company, Daqing 163714, China)  
The transparent polypropylene(PP) special material for injection is prepared by adding nucleating agent to homopolymerized PP matrix. Not only the optical property but also the rigidity of homopolymerized PP is improved by adding nucleating agent, and the processing performance is improved. In order to decrease the product cost and increase the properties of transparent PP, the nucleating agent composite is developed. The properties of transparent PP containing this nucleating agent meet the technical index. And the effects of processing temperature and resin MFR on the optical property of transparent PP property are discussed.
