Owens Corning (owenscorning.com) has developed “Hydro-Strand,” a chopped-strand glass fiber for reinforcing high-end polyphenylene sulfide (PPS) composites. It’s designed to be used as an alternative to metal in applications that come into contact with high-temperature fluids, such as thermostat covers, impellers and pumps. Compared to standard PPS, those that are HydroStrand-reinforced feature:
• Superior mechanical strength.
• Hydrolysis resistance at temperatures exceeding 130º C.
• A 35% performance improvement when subjected to hot water or glycol aging.
