Polyolefin and composition for pipe systems and sheets |
摘要 |
A polyolefin composition comprising (percent by weight): A) from 7% to 19%; of a copolymer of propylene and 1-hexene wherein said copolymer contains less than 1% of recurring units derived from hexene-1; B) from 81% to 93% of a heterophasic polypropylene composition comprising: B1) from 86% to 95% of a propylene homopolymer, said propylene polymer being insoluble in xylene at room temperature in an amount over 85% having a polydispersity Index ranging from 3 to 10; and a Melt Index from 0.5 to 10 dg/min; B2) from 5% to 14% of a copolymer of ethylene and propylene having an ethylene derived units content ranging from 50% to 65%; said polymeric composition having a Melt Index from 0.05 to 10 dg/min. |
