High Performance > 300°F | Polyphenylene Sulfide (PPS)


TECATRON™ PPS is a high performance thermoplastic that combines good mechanical properties with excellent thermal and chemical resistance properties. There is no known solvent that dissolves TECATRON™ PPS at temperatures below 392°F. Its low ionic impurities make it an excellent choice for applications where high purity is a concern. TECATRON™ GF40 is a glass reinforced material that offers extremely high strength along with excellent chemical resistance properties. TECATRON™ PVX is a bearing grade PPS that is suitable for high load applications.

  • High purity characteristics
    Low ionic impurities are apparent.
  • Outstanding retention of mechanical properties under continuous use up to 338°F (170°C)
  • Excellent chemical resistance
  • Good electrical insulator
  • High mechanical strength
  • High strength-to-weight ratio
  • Corrosion resistant
  • Dimensional stability over wide variations of temperature and moisture
  • Creep resistance
    Long-term property retention.

TECATRON™PPS's excellent thermal and chemical resistance along with its ionic impurities make an excellent choice for applications requiring low outgassing and high purity. TECATRON™PPS is typically used in the automotive, electrical/ electronic, industrial, mechanical, appliance and semiconductor industries.
