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.
