Techtron Lubricated Polymer: Sheets, Rods & Tubes
Techtron PPS is an internally lubricated polyphenylene sulphide grade which demonstrates an excellent combination of properties, making it ideal for applications where PA, POM, PET, PEI and PSU fall short, or where PBI, PI, PEEK and PAI are over-engineered and a more economical solution is required.
Techtron HPV PPS offers a valuable combination of properties including wear resistance, load-bearing capabilities and dimensional stability, when exposed to chemicals and high temperature environments.
- Very high maximum allowable service temperature in air (220°C continuously, going up to 260°C for short periods of time)
- High mechanical strength, stiffness and creep resistance, also at elevated temperatures
- Excellent wear and frictional behaviour
- Excellent chemical and hydrolysis resistance
- Very good dimensional stability
- Good electrical insulating and dielectric properties
- Inherent low flammability
- Excellent resistance against high energy radiation (gamma and X-rays)
- Physiologically inert (suitable for food contact)
Techtron PPS Technical Notes
All 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 Proven Applications
Components used in high pressure liquid chromatography are fabricated from Techtron PPS stock shapes due to its biocompatibility and chemical resistance. (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 materials: Vespel* PI)
Rings made of Bearing-grade Quadrant PPS eliminate galling and corrosion problems in centrifugal mining pumps, and allow closer running clearances - reducing recirculation and increasing efficiency. (Prior material: Bronze)
Precision machined, 40% Glass-reinforced Quadrant PPS components allow high efficiency in a broad range of chemical pump environments. (Prior material: Stainless Steel)
From 100°C onwards (above the glass transition temperature), the mechanical properties of Techtron HPV PPS drops off significantly and the coefficient of linear thermal expansion increases considerably. Ketron® PEEK and Torlon® PAI may be suitable alternatives to overcome these inconveniences.
