FILLED POLYOLEFIN COMPOSITIONS

摘要

Filled polyolefin compositions comprising: A) from 20% to 80% by weight of a polypropylene component; B) from 20% to 80% by weight of a filler; wherein the percentages of A) and B) are referred to the sum of A) and B), and A) is selected from the following compositions: a) a polypropylene composition containing from 20% to 80% by weight of a polypropylene fraction A^I) having a Melt Flow Rate value of 500 g/10 min. or more, and from 20% to 80% by weight of a polypropylene fraction A^II) having a Melt Flow Rate value of from 0.1 to 30 g/10 min., the said percentages of A^I) and A^II) being referred to the sum of A^I) and A^II); or b) a polypropylene composition containing from 15% to 72% by weight of a polypropylene fraction A^I) having a Melt Flow Rate value of 500 g/10 min. or more, from 15% to 70% by weight of a polypropylene fraction A11) having a Melt Flow Rate value of from 0.1 to 30 g/10 min. and from 0.5% to 15% by weight of a compatibilizer Q), the said percentages of A^I), A^II) and Q) being referred to the sum of A^I), A^II) and Q).
