Owens Corning’s HydroStrand is a chopped strand glass fiber for high-performance polyphenylene sulfide (PPS) composites. Available globally, the glass fiber is designed for use in automotive and industrial applications that come in direct contact with high-temperature fluids. HydroStrand 918A reinforcements provide a new level of mechanical strength and hydrolysis resistance in PPS composites designed for use in applications exposed to aggressive high-temperature fluids such as cooling modules, thermostat covers, impellers, and pumps, and provides an alternative to metal. According to the company, using HydroStrand glass fiber in PPS composite solutions improves performance up to 35% after hot water or glycol aging. An automotive cooling system part (pictured) is an application example for HydroStrand fiber.
