Abstract

Tubes formed from a propylene based composition having a flexural modulus of elasticity of 1,400 to 2,000 MPa and a melt flow index of 0.1 to 1 g/10 minutes, including: from 80 to 97 parts in weight of a propylene homopolymer (A) having an isotacticity index of at least 0.96, and from 20 to 3 parts in weight of a statistical copolymer of propylene (B) containing from 45% to 70% ethylene by mole and/or an alpha olefin containing from 4 to 8 atoms of carbon, the ratio of the intrinsic viscosity of polymer (B) to polymer (A) being at least 1.55 and less than or equal to 3.
