PPS (Polyphenelynesulfide) offers the broadest resistance to chemicals of any advanced engineering plastic.
Several grades of PPS exist, including RYTON (Unfilled or Bearing-Grade) and TECHTRON (Unfilled, 40% Glass-Reinforced or High-PV). Additional grades include SUSTATRON (Unfilled or 40% Glass-Reinforced) and TECATRON (Unfilled, Bearing-Grade or Hydrolysis-Resistant).
These various grades of the PPS resin allow for chemical resistance, high temperature stability, zero moisture absorption, excellent dimensional stability, ultra-low wear factors and structural strength. PPS materials also offer low flammability ratings of V-O/5VA.
