Specialty Polymers for Plumbing Applications

Solvay’s family of specialty polymers for use in the plumbing industry are durable, chemically resistant, and corrosion free to contribute to an easier installation process and a more sustainable plumbing system. Our high-performing plastics are specially formulated to combine low water absorption and extreme toughness with chemical inertness and thermal stability to deliver long-term performance in harsh environments. Traditional metal-based components for plumbing systems are easily susceptible to corrosion and contamination. Accordingly, OEMs demand tough, cost-competitive alternatives to increase performance and ensure safety for plumbing parts and products.


Solvay's specialty polymers are capable of enduring more than 50 years of exposure to high-pressure and high-temperature water. These materials are ideally suited for medium to long-term plumbing applications. Our comprehensive range of chemically resistant, corrosion free specialty polymers has advanced the plumbing industry in reliable product performance and level of water purity to help achieve Drinking Water Approved certifications. The advanced properties of Solvay's line of specialty polymers set the standard of the quality and production of injectable and moldable materials for plumbing applications such as valves, fittings, manifolds, water meters and pumps. 

Solvay meets the highest industry standards for: Corrosion resistance • No scale deposit • No biofilm adhesion • No contamination by heavy metals • Ease of assembly • Low noise • Good thermal insulation • Lower cost • Reduced environmental footprint.

Specialty Polymers Protect Water Purity

Plumbing systems must maintain high purity levels to meet the stringent industry standards for health and safety. We voluntarily certify all of our products for Drinking Water Approval, even in harsh chemical and extreme temperature plumbing environments. Our specialty polymers enact the highest levels of chemical inertness and hydrolytic stability to ensure long-term assurance of water potability. 

Solvay engineers have formulated high-quality polymers to outperform traditional metals for water purity by eliminating the concern of heavy metal contamination in drinking water systems. Beyond metal contamination, our high chemically and thermally sustainable polymers also lead the industry in resistance to harmful biofilm adhesion typically found in lower quality plastics and metal parts. For example, Solvay’s Radel® PPSU (polyphenylsulfone) has extreme hydrolytic stability over conventional polyamides to advance potable water potential in piping systems. 

Drinking Water Agency Approvals



Long-term Reliable Performance of Specialty Polymers

Intricate plumbing systems do not facilitate easy or continual entry for the replacement of parts. In response to behind the wall plumbing systems that are difficult to access, Solvay offers dimensionally and thermally stable polymers that outlast lower grade thermoplastics and traditional metal parts to prolong expected system life cycle and minimize the need for regular interaction with the plumbing components. 

Solvay’s highly durable polymers withstand chemical, thermal and mechanical distress. They guarantee no scale deposit, low creep and resistance to corrosion, temperature and oxidative aging. For example, Ryton® PPS combines chemical and dimensional stability with extremely low viscosity to allow for injection molding for thin-walled plumbing parts that endure extremely high temperatures. 

Typical operating temperatures



Specialty Polymers Outperform Metal

Traditional metal plumbing components are susceptible to corrosion that eventually builds scale deposit and infiltrates drinking water after long term exposure to harsh chemicals and extreme temperatures. Implementing specialty polymers as a replacement to metal reduces or eliminates all common metal-based concerns. Solvay’s polymer formulas also reduce noise, enable better thermal insulation and lessen the overall environmental footprint of plumbing systems when compared to any traditional metal plumbing product. These advanced thermoplastics guarantee durable, chemically resistant and hydrolytically stable properties and provide OEMs with long-lasting and cost-competitive materials for use in today’s plumbing systems.
