Effect of Processing Aids on the Performance of High Filled Polypropylene

In this paper, we mainly introduces the influence of the processing aids TR131 which namely the lubricating and dispersion agents on the properties of high filled polypropylene. The experiment compared the melt flow rate, tensile strength, bending strength and impact strength of the high filled polypropylene with processing aids TR131 and without it. The results show that high filled polypropylene with Calcium Carbonate could improve the bending strength and impact strength of the pure polypropylene, but the melt flow rate and tensile strength decreased. Incorporation of processing aids TR131 could improve the melt flow rate and the tensile strength of the high filled polypropylene.
