MANUFACTURED under a quality system approved to ISO 9002, Ertalyte is precision-fabricated to individual customers' requirements by plastics engineering company Dotmar EPP .
Dotmar's applications development engineer Aldo Mostacci says Ertalyte offers a high mechanical strength, stiffness and hardness, very good creep resistance, and a low and constant coefficient of friction.
In addition, Ertalyte is physiologically inert.
"Ertalyte's innovative properties make the material ideally suitable for the manufacture of mechanical precision parts which have to sustain high loads and/or are subject to wear," says Mr Mostacci.
Typically such parts include bearings, bushings, wear plates, thrust washers, guides, gears, rollers, sheaves, pump components, valve parts and electrical insulating components.
For unlubricated moving part applications, the manufacturer of semi-finished and finished engineering thermoplastics markets a premium, internally lubricated bearing grade called Ertalyte TX.
Incorporating a uniformly dispersed solid lubricant, Ertalyte TX is particularly suitable for the manufacture of sliding parts where low friction, long wear, high load-bearing capacity and a very good dimensional stability are required.
Application examples include precision engineering and machine construction.
Ertalyte TX has superior wear resistance, a lower coefficient of friction and very high pressure-velocity capabilities, says Mr Mostacci.
At the same time, there is good chemical resistance (with the exception of alkaline solutions), very good machineability, moderate impact strength and good electrical properties.
Ertalyte TX retains the tensile and compressive strength, stiffness, hardness, creep resistance and dimensional stability inherent in the Ertalyte design.
However, toughness is slightly reduced, though without affecting notch sensitivity.
The Ertalyte series, which forms part of the Quadrant EPP family of engineering plastics stock shapes, is available as rods (10mm - 150mm), sheets (thickness 8mm - 100mm) and tubes (outside diameter 20mm - 200mm).
Dotmar EPP can also supply non-standard configurations on request.
