In some cases (e.g. PA and PPA alike materials), the hot water attacks the polymer as such eventually leading to a complete loss of mechanical properties. Very often, this goes hand in hand with strong swelling effects. To support customers in the development of applications in contact with coolants, the European Ryton® International Technical Center (ITC) heavily invested in state of the art test equipment, including pressure vessels for aging tests. The temperature and pressure in these vessels are continuously monitored and registered. The complete system is regularly calibrated by an independent lab and the whole set up has been subjected to different audits from Tier 1 suppliers. As a result, some of these system suppliers accept data generated at the Ryton® ITC as if they were generated in their own labs. Because of the close collaboration between the Ryton® ITC and the leading coolant manufacturers, Chevron Phillips Chemical can anticipate on new coolants before they even come on the market. DIMENSIONAL CHANGE For polymers that have a good resistance versus hot water, water does not attack or dissolve the polymer, but it may seep down the interfaces between the polymer matrix and the glass fiber reinforcement and break down molecular linkages between the polymer and the glass. When the adhesion between the polymer and the glass fiber reinforcement is compromised, the compound will lose a significant degree of strength. Width Thickness Although differences in filler and additive systems 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-4-220 PPS and BR111-S PPS have been specially formulated for enhanced resistance to the detrimental effects of water at elevated temperatures and therefore tend to retain a greater degree of mechanical strength over long-term exposure to high temperature engine coolants, especially the more aggressive new “long-life” (OAT) coolants.
