SOLVAY’s high-performing Radel® polyphenylsulfone (PPSU) polymer has enabled China-based CiXi Zhenpeng Plumbing Fittings Company to replace traditional brass in a new line of all-plastic valves targeting pressurized hot water systems used in heating, ventilation and air conditioning (HVAC) applications.

Among Zhenpeng’s new products is the industry’s first all-PPSU stop valve to meet standards tested by the International Association of Plumbing and Mechanical Officials (IAPMO). Solvay’s high-performance polymer also enabled a patented one-piece ball valve and valve rod design, a half-ball valve, and L-type and T-type valves. Solvay’s Radel PPSU offers high fatigue resistance, strong chemical resistance and high impact strength, as well as the highest long-term hydrostatic strength (LTHS) of any sulfone polymer, making it well-suited for fittings used in multilayer piping systems that can operate under high pressure (up to 10 bar) and temperatures up to 95°C.
