Abstract
The present disclosure provides a composition, and pressure pipes produced therefrom, comprising a multimodal high-density polyethylene and from about 0.10% to about 0.30% nucleating agent to improve the barrier property of high-density polyethylene pressure pipes to COgas. The pressure pipes produced with this composition will convey COgas with reduced permeation rates in the range of from about 30% to about 40% compared to control high-density polyethylene pressure pipes made from the same multimodal high-density polyethylene that does not contain nucleating agent.
