Abstract: A polyolefin composition made using a propylene/ethylene copolymer (90.0 wt % to 99.0 wt %) and a heterophasic (second) propylene/ethylene copolymer (1.0 wt % to 10.0 wt %). The composition is useful for the production of pressure pipes, e.g., for use at low temperature, and of pipes for use in heat radiating systems, among other applications. The propylene/ethylene copolymer has between 1.0 wt % and 8.0 wt % ethylene derived units. The second propylene/ethylene copolymer is made using (1) a propylene homopolymer or a propylene/ethylene copolymer (12 wt % to 52 wt %) and (2) a propylene ethylene copolymer (48 wt % to 88 wt %) that has a content of ethylene derived units ranging from 15.0 wt % to 42.0 wt %.
