Ertalyte [PET: Polyethylene Terephthalate]
This is made of crystalline polyester with properties characterized by high rigidity and strength. Abrasion resistance is higher than those of Nylon and Acetal.
Main Characteristics:
- High mechanical strength, stiffness and hardness
- Very good creep resistance
- Low and constant coefficient of friction
- Excellent wear resistance (comparable with or even better than nylon grades)
- Very good dimension stability (better than polyacetal)
- Excellent stain resistance
- Better resistance to acids than nylon and polyacetal
- Good electrical insulating properties
- Physiologically inert (suitable for food contact)
- Good resistance to high energy radiation (gamma- and X–rays)
Applications:
Heavily loaded bearing (brushings, thrust washers, guides, etc.), dimensionally stable parts for mechanism of precision (brushings, slideways, gears, rollers, pump components, etc.) and insulating components for electrical engineering.
ERTALYTE [natural (white) / black]
The specific properties of this virgin crystalline PET make it specially suitable for the manufacture of mechanical precision parts which have to sustain high loads and/or are subject to wear.
ERTALYTE TX [pale grey]
This is a polyethylene terephtalate compound incorporating a uniformly dispersed solid lubricant. Its specific formulation yields a premium, internally lubricated bearing-grade. ERTALYTE TX 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.
