The invention relates to a foamable polymeric composition, comprising a thermoplastic elastomer on the basis of a polyolefin and a rubber; the invention is characterized in that the polyolefin is a polypropylene homo- or copolymer having: a weight average molecular weight, MW, of at least 2*105; and an elongational viscosity (measured at a temperature of 170 °C, at a rate of elongation of 0.03 s-1 and at a time of 10 s), EV(170/10), of at least 1.4*105 Pa.s. The invention relates also to a process for foaming a polymeric composition, as well as to a foamed thermoplastic article. |
