Pipes and Fittings Polymer Pipes - Plastics Provide Enhanced Mechanical Properties with Higher Standards Plastic-based piping systems offer several benefits, along with some limitations, compared to metallic and other non-polymeric pipe materials. Chemical resistance, low weight, availability of parts, the cost to performance ratio, long-term creeping under mechanical stress, and electrical and thermal insulating characteristics are the advantages of polymer piping systems. Pipes and fittings in plumbing systems must keep high performance despite exposure to continuous water flow, changing temperature, and oxidizers. Polymer stabilizers such as primary and secondary antioxidants and light stabilizers additives provide a long-lasting properties formulation for hot water and high mechanical load applications that offer outstanding resistance to corrosion and failure.
