Quadrant Surlon stock shapes made of crystalline polyester polymers, are marketed under the trade names ERTALYTE (virgin grade) and ERTALYTETX (filled grade). Its applications include manufacturing of heavily loaded bearings (bushings, thrust washers, guides, etc.), dimensionally stable parts for mechanisms of precision (bushings, slide-ways, gear, rollers, pump components, etc.) and insulating components for electrical engineering.
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 dimensional 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)
