Solvay Specialty Polymers, a manufacturer of high-performance polymers, with many locations throughout the US, recently announced that two Ryton® polyphenylene sulfide (PPS) grades have been certified for drinking water contact according to NSF 61 (USA), WRAS (UK), W270 DVGW and KTW (Germany), ACS (France), and DM 174 (Italy).
The two new Ryton PPS grades aim to replace metals as well as competitive engineering plastics, and address major challenges for end-products in potable water processing, such as heat and water meters, water pumps, boiler components, faucets, cartridges, along with balancing and other valves.
