Ryton® PPS




Ryton® PPS is an ideal choice for automotive parts exposed to high temperatures, automotive fluids, or mechanical stress. Typical applications include under hood components, brake systems, and electrical/electronic devices requiring high heat resistance, high dimensional stability, and corrosion resistance. 

Ryton® PPS is a lighter weight alternative to metals that is resistant to corrosion by salts and all automotive fluids. The ability to mold complex parts to tight tolerances and insert molding capability accommodates multiple component integration. 

In Automotive, Ryton® PPS is used in components required to withstand high temperatures, mechanical stress and corrosive automotive fluids. By replacing metal, Ryton® PPS reduces fuel consumption, lowers costs and improves system integration.

In Green Hydrogen, Ryton® PPS is well-suited for cell frames found in alkaline electrolyzers. It offers thermal, mechanical, dimensional and chemical stability for components in fuel cell systems allowing optimization of the structural components of unit cells. Ryton® PPS can also be used for various valves and hydrogen loop tubes.

Ryton® PPS provides excellent lightweighting benefits, resistance properties and mechanical performance for electrolyzer cell frames in alkaline electrolysis (AEC).  It can also be precision molded to tight tolerances with a high level of reproducibility for serial production.

The low leach-out behavior of Ryton® PPS plus superior thermal, mechanical and dimensional stability make it ideal for use in PEM fuel cell systems for end plates, high- and low-pressure H2 lines, as well as balance of plant air systems and thermal management systems.
