Impact-Modified Polypropylene Composite

摘要

An impact-modified polypropylene composite is made by mixing from 65 to 97 weight parts polypropylene having a glass transition temperature of greater than−25° C., from 3 to 35 weight parts propylene-based elastomer having a density of from 0.860 g/cc to 0.875 g/cc, a melting point of from 130° C. to 170° C., a glass transition temperature of from−35° C. to−25° C., and a melt flow rate of from 3.0 to 15.0 g/10 minutes, and from 0.1 to 20 weight parts of exfoliated silicate platelets.
