Abstract:
The invention relates to a biaxially oriented pipe made of a polymer composition comprising a propylene-based polymer, wherein the propylene-based polymer comprises A) a heterophasic propylene copolymer, wherein the heterophasic propylene copolymer consists of (a1) a propylene-based matrix, wherein the propylene-based matrix consists of a propylene homopolymer and/or a propylene copolymer consisting of at least 70 wt % of propylene monomer units and at most 30 wt % of ethylene and/or α-olefin monomer units, based on the total weight of the propylene-based matrix and (a2) a dispersed ethylene-α-olefin copolymer, wherein the sum of the total amount of propylene-based matrix and total amount of the dispersed ethylene-α-olefin copolymer in the heterophasic propylene copolymer is 100 wt %, wherein the amount of (a2) with respect to the propylene-based polymer is 2.0 to 30.0 wt %.
