Ticona (Kelsterbach, Germany) has introduced Fortron 6162XF, a mineral/glass-fiber-reinforced polyphenylene sulfide (PPS) that offers potential weight savings of up to 50 percent vs. metal. In 1,000-hour exposure tests at 194°F/90°C, the material reportedly exhibited good fuel resistance, with a weight change of less than 1 percent. Applications, therefore, can include impellers, outlet covers and fuel-injector components. The material’s continuous-use temperature is high: 320°F to 464°F (160°C to 240°C). For short periods, it can withstand up to 518°F (270°C), retaining chemical- and creep-resistance as well as dimensional stability, with virtually no moisture absorption (≤0.02 percent).
