A kind of high flow and impact copolymerized polypropylene grade YPJ-630H for automotive interior parts was successfully developed in a 200 kt/a gas phase method polypropylene plant by hydrogen regulation method. The performances of YPJ-630H were studied and compared with YPJ-630 prepared by chemical degradation method and its imported counterpart. The results show that the performances of YPJ-630H meet the design requirements. In comparison with YPJ-630 and its imported counterpart, the impact strength of YPJ-630H is increased by 5%-10%, and it has broader relative molecular mass distribution, better processing performance and strong potential applications.
