PPS (Polyphenylene Sulfide) is a high performance thermoplastic that combines good mechanical properties with excellent thermal and chemical resistance properties. There is no known solvent that dissolves PPS at temperatures below 392°F. Its low ionic impurities make it an excellent choice for applications where high purity is a concern. PPS GF40 (commonly referred to as Ryton) is a glass reinforced material that offers extremely high strength along with excellent chemical resistance properties. There is also bearing grade PPS that is suitable for high load applications. PPS is typically used when because of its outstanding retention of mechanical properties under continuous use up to 338°F (170°C), excellent chemical resistance and good electrical insulator performance. PPS also provides high mechanical strength and strength-to-weight ratio while maintaining dimensional stability over wide variations of temperature and moisture with long-term property retention.
