Patent ID: 8623932

Claim:
An article comprising: a foamed polyolefin composition comprising (all percent amounts being by weight): (A) 50%-90% of a polypropylene component comprising: (A I ) from 25% to 75% by weight, based upon the total weight of (A), of a propylene polymer having a melt flow rate MFR I of from 0.1 to 10 g/10 min.; and (A II ) from 25% to 75% by weight, based upon the total weight of (A), of a propylene polymer having a melt flow rate value MFR II of at most 100 g/10 min.; wherein the ratio MFR II /MFR I is from 5 to 60 and the propylene polymers (A I ) and (A II ) are independently selected from the group consisting of a propylene homopolymer, a random copolymer of propylene containing up to 3% of ethylene, and a random copolymer of propylene containing up to 6% of at least one C 4 -C 10 α-olefin and optionally up to 3% of ethylene; the amounts of (A I ) and (A II ) being referred to the total weight of (A I ) and (A II ) wherein (A) has a polydispersity index from 4 to 7; and (B) 10%-50% of a copolymer component of ethylene and at least one C 3 -C 10 α-olefin, the copolymer containing from 15% to 50% of ethylene, and (C) optionally 0.5 to 10 weight %, based upon the weight of (B), of a diene; the amounts of (A) and (B) being referred to the total weight of (A) and (B); said composition having a value of viscosity [η] of the fraction soluble in xylene at room temperature of 3.5 to 9 dl/g.
