Polyester Plastics: Rods & Sheets
Stock shapes made of crystalline thermoplastic polyester, trade names Ertalyte (virgin grade) and Ertalyte TX (bearing grade).
Polyester PET Rod is a good alternative to Delrin, as it absorbs less moisture, therefore holds it shape much more easily.
Ertalyte polyester is usually used to create precision parts which have to sustain high loads and high wear due to its properties. Ertalyte TX is internally lubricated bearing-grade polyester that offers an even lower coefficient of friction when compared to other polyester plastics.
Ertalyte PET Characteristics
- High mechanical strength
- Very good creep resistance
- Low and constant coefficient of friction
- Excellent wear resistance (comparable to or even better than nylon grades)
- Very good dimensional stability (better than polyacetal)
- Physiologically inert (suitable for food contact)
- Excellent stain resistance
- Better resistance to acids than nylon and polyacetal
- Good electrical insulating properties
- Good resistance against high energy radiation (gamma-and X-rays)
Ertalyte (PET) natural / black
The specific properties of this virgin crystalline Polyester PET make it especially suitable for the manufacture of mechanical precision parts which have to sustain high loads and/or are subject to wear.
Ertalyte TX (PET + solid lubricant) pale grey
Ertalyte TX is a polyethylene terephtalate compound incorporating a uniformly dispersed solid lubricant. Its specific formulation yields a premium, internally lubricated bearing-grade Polyester. Ertalyte TX Polyester has not only an outstanding wear resistance, but offers in comparison with Ertalyte an even lower coefficient of friction as well as higher Pressure-Velocity capabilities.
