Ertalyte® Key Properties
Ertalyte®'s properties make it especially suitable for the manufacture of precision mechanical parts which are capable of sustaining high loads and enduring wear conditions. Ertalyte® TX is an internally lubricated thermoplastic polyester providing enhanced wear and inertness over general purpose nylon(PA) and acetal (POM) products. Containing uniformly dispersed solid lubricant, Ertalyte® TX provides a lower wear rate and coefficient of friction than unmodified polyesters like PET or PBT and even internally lubricated materials like Delrin® AF blend. Both Ertalyte® natural and black, and Ertalyte TX are
FDA compliant. Natural Ertalyte® is also USDA, 3A-Dairy and Canada AG compliant.

Dimensional Stability Comparison of Common Engineering Plastics
Ertalyte® offers superior dimensional stability with a combination of low moisture absorption and a low coefficient of linear thermal expansion (CLTE), the graph below highlights how it compares to other engineering plastics like Acetal, Nylon Type 6/6, and UHMW-PE.
Increased Stiffness and Improved Wear Resistance
Ertalyte® offers higher stiffness at elevated temperatures when compared to other engineering plastics, as shown in the Dynamic Modulus (DMA) graph below. In addition, the Ertalyte® TX grade offers improved wear resistance over common engineering plastics, as shown in the below chart.
Ertalyte® Available Grades
 | - Ertalyte® PET-P Natural - is natural an unreinforced, thermoplastic polyester based on polyethylene terephthalate (PET-P). It is characterized as having excellent dimensional stability coupled with excellent wear resistance, a low coefficient of friction, high strength, and resistance to moderately acidic solutions. Its low moisture absorption enables mechanical and electrical properties to remain virtually unaffected by moisture. Ertalyte® is FDA-compliant in natural and black. Natural Ertalyte® is also USDA, 3A-Dairy, and Canada AG compliant.
|
 | - Ertalyte® PET-P Black - is a black unreinforced, thermoplastic polyester based on polyethylene terephthalate (PET-P). It offers the same properties as natural but in black. Ertalyte® is FDA-compliant in natural and black.
|
 | - Ertalyte® PET-P TX - is an internally lubricated thermoplastic polyester providing enhanced wear and inertness over general purpose nylon(PA) and acetal(POM) products. Containing uniformly dispersed solid lubricant, Ertalyte® TX PET-P provides a lower wear rate and coefficient of friction than unmodified polyesters like PET or PBT and even internally lubricated materials like Acetron® AF POM-H. Ertalyte® TX PET-P excels under both high pressure and velocity conditions. It is also ideally suited for applications involving soft metal and plastic mating surfaces. Ertalyte® TX is FDA-compliant.
