Techtron Lubricated Polymer: Sheets, Rods & Tubes

Techtron Characteristics

• 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 Availability

Techtron HPV PPS (Polyphenylene sulphide) deep blue

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, it 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 can cause premature wear of the counterface in moving-part applications.

The material can be used in all kinds of industrial equipment such as industrial drying and food processing ovens (bearing, roller etc), chemical process equipment (pump, valve & compressor components) and electrical insulating systems.

Techtron HPV PPS Proven Applications

HPLC

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)

Testing fixtures

Socket assemblies extensively machined from Techtron PPS plate are used during high power/high speed testing of semiconductor packages. (Prior materials: Vespel* PI)

Lantern Rings

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)

Pump Housings

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.
