Techtron HPV PPS
This reinforced, internally, lubricated polyphenylene sulphide grade 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 finds its applications where PA, POM, PET, PEI and PSU 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 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 fibre reinforced PPS which causes premature wear of the counterface in moving-part applications. It goes without saying that these features, in combination with its excellent chemical resistance, offer numerous application possibilities for TECHTRON HPV PPS in all kinds of industrial equipment such as industrial drying and food processing ovens, chemical process equipment and electrical insulating systems.

Applications
- Lantern rings
- Rings made of Bearing-grade Techtron HVP PPS eliminate galling and corrosion problems in centrifugal mining pumps, and allow closer running clearances reducing recirculation and increasing efficiency.
- Pump housings
- Precision machined, 40% Glass-reinforced Techtron HVP PPS components allow high efficiency in a broad range of chemical pump environments.
- HPLC
- Components used in high pressure liquid chromatography are fabricated from Techtron HVP PPS stock shapes due to its chemical inertness.
- Chip Nests
- Socket assemblies extensively machined from Techtron HVP PPS plate are used during high power/ high speed testing of semiconductor packages.
- Retaining Rings
- Retaining rings used to hold wafers in place in chemical mechanical polishing equipment are fabricated from TechtronŽ HVP PPS.
- Solvent extractor conveyor bushings
- Continuous solvent extractors use aggressive chemicals to extract oil or sugar from the meal. The Techtron HVP PPS bushings for the rollers of the screen transporting the meal are continuously submerged in the solvent. Under these impossible to lubricate conditions, wear resistant Techtron HVP PPS provides a long lasting maintenance free solution.
- Insulating printer bearings
- Techtron HVP PPS is used as electrically insulating bearings for industrial recto verso printers offering a maintenance free solution.
