Techtron ® PPS Key Properties & Grades
Techtron PPS (polyphenylene sulfide) products offer the broadest resistance to chemicals of any advanced engineering plastic. They have no known solvents below 392°F (200°C) and offer inertness to steam, strong bases, fuels and acids. Minimal moisture absorption and a very low coefficient of linear thermal expansion, combined with Quadrant’s proprietary stress relieving processes, make these PPS products ideally suited for precise tolerance machined components. In addition, PPS products exhibit excellent electrical characteristics and are inherently flame retardant.
- EXCEL IN CORROSIVE ENVIRONMENTS TO 425°F (220°C)
- Excellent chemical resistance
- Essentially zero moisture absorption
- Machines to tight tolerances
- Excellent alternative to PEEK at lower temperatures
Techtron PPS Extruded Virgin - offers the broadest resistance to chemicals of any advanced engineering plastic. They have no known solvents below 392°F (200°C) and are inert to steam, strong bases, fuels and acids. Minimal moisture absorption and a very low coefficient of linear thermal expansion, combined with stress-relieving manufacturing, make PPS ideally suited for precise tolerance machined components. As an unfilled material, Techtron® is easily machined to close tolerances. It is ideal for structural applications in corrosive environments or as a lower-temperature replacement for PEEK. Standard Techtron® PPS is off-white in color.
Techtron HPV PPS Extruded Bearing Grade - exhibits excellent wear resistance and a low coefficient of friction. It overcomes the disadvantages of virgin PPS caused by a high coefficient of friction, and of glass fiber reinforced PPS which can cause premature wear of the counter face in moving-part applications.
Techtron PSBG PPS Compression Molded Bearing Grade - is internally lubricated and carbon fiber reinforced compression molded PPS offering a low coefficient of thermal expansion and uncompromised chemical resistance. It is well suited for and wear applications or when an electrically conductive material is required.
Techtron PSGF PPS Compression Molded 40% Glass Filled - is a compression molded analogue to Ryton R4 resin. It offers better dimensional stability and thermal performance than Techtron® PPS and maintains its strength to above 425°F (220°C).
