Polypropylene is a thermoplastic polymer that is produced from the monomer propylene. Polypropylene is used in several types of pipes including sewage and drainage, gas distribution, plumbing, and potable water transport. Polypropylene water pipes are primarily manufactured as extrusion products that have a fixed cross-sectional profile; which is important when distributing volumes of liquids at varying levels of pressure. Polypropylene water pipes typically contain antioxidants and stabilizers in order to protect against thermal instability and oxidation. Chlorine is often added to potable water in order to prevent microbial growth. The chlorine can react with antioxidants in the pipe, which leads to leaching of the antioxidant degradants into the water. Over time this reaction degrades antioxidants, resulting in increased oxidation of the pipe material and overall mechanical instability. See the Process Chemistry tab for leachants that were identified in our research.
