Material Description

Polyphenylene Sulfide (PPS) offers the broadest resistance to chemicals of any advanced engineering plastic.  They have no known solvents below 392°F and are inert to steam, strong bases, fuels, and acids.  PPS is ideal for precise tolerance machined components because it has minimal moisture absorption and a very low coefficient of linear thermal expansion.

Notable Material Features

  • Minimal moisture absorption
  • Very low coefficient of linear thermal expansion

Grades of PPS

Ryton® 40% Glass Reinforced PPS

Ryton®, Glass filled PPS, is the most recognized filled grade of PPS.  Glass filled PPS has better dimensional stability and thermal performance than unfilled Techtron® PPS and maintains its strength to above 425°F.  Ryton® is a trade name of Chevron Phillips Chemical.

Ryton® Bearing Grade PPS

Ryton®, Bearing grade PPS, is internally lubricated and is carbon fiber filled, offering a low coefficient of thermal expansion and uncompromised chemical resistance.  Bearing grade Ryton® can be used for thrust or wear applications and when an electrical conductive material is required.

Techtron® PPS

Techtron® PPS is made by Quadrant EPP USA, Inc.  Unfilled Techtron® is easily machined to close tolerances.  Techtron® PPS can be used for structural applications in corrosive environments and as a lower-temperature replacement for PEEK.  Standard Techtron® is off-white in color, but it is also available in black as a compression molded version.
