Ryton® PPS - Resistance to Automotive Fluids

Extensive test data demonstrates that Ryton® PPS compounds, regardless of the filler and/or additives used, are virtually impervious to all common automotive fuels (including alcohol-containing flex fuels), lubricating oils, transmission fluids, brake fluids, and other hydraulic fluids. Although differences in fillers and additives can affect resistance to engine coolants, Ryton® PPS compounds are generally very resistant to glycol-based and silicone containing coolants, even at elevated temperatures.

Ryton® R-4-220NA is specially formulated for enhanced resistance to the detrimental effects of water at elevated temperatures (see Hot Water), and therefore tends to retain a greater degree of mechanical strength over long-term exposure to high temperature engine coolants, especially the more aggressive "OAT" and "hybrid" type “long-life” engine coolants.
