Unlike reinforced PPS products, Techtron PPS is easily machined to close tolerances. It is ideal for structural applications in corrosive environments or as a PEEK replacement at lower temperatures. Techtron PPS is white in colour.
PPS (polyphenylene sulfide) products offer the broadest resistance to chemicals of any advanced engineering plastic. They have no known solvents below 200 °C (392 °F) 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.
All Quadrant-EPP's PPS products offer dimensional stability and strength at moderate temperatures. They are rated for continuous service to 220 °C (425 °F), but strength and stiffness vary based on temperature and grade. Unreinforced Techtron PPS is generally not recommended for wear applications. Products like Duratron® PAI or Ketron® PEEK are better selections for high temperature wear applications. When designing with compression molded grades, it is important to note its relatively low elongation and impact strength.
Techtron HPV PPS (colour: deep blue) demonstrates an excellent combination of properties including wear resistance, load-bearing capabilities and dimensional stability when exposed to chemicals and high temperature environments.
Techtron HPV PPS is found in applications where PA, POM, PET and other plastics fall short or where PI, PEEK and PAI are over-engineered and a more economical solution must be found.
Thanks to the uniformly dispersed internal lubricant, Techtron HPV PPS exhibits an 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 a glass fiber reinforced PPS which causes premature wear of the counterface in moving-part applications.
Techtron HPV PPS can be used in all kinds of industrial equipment such as industrial drying and food processing ovens (bearings, rollers, ...), chemical process equipment (pump-, valve & compressor components) and electrical insulating systems.
Techtron HPV PPS (rods, plates, tubes) is available as a "Food Grade".
Components used in high pressure liquid chromatography are fabricated from Techtron PPS stock shapes due to its chemical inertness. (Prior materials: PEEK, Stainless Steel, Titanium)
Socket assemblies extensively machined from Techtron PPS plate are used during high power / high speed testing of semiconductor packages. (Prior material: Vespel® PI)
Retaining rings used to retain wafers in chemical-mechanical polishing equipment are fabricated from Techtron PPS.
