PTFE composites with ultra-low wear rate

(24-09-2021) Levente Tóth developed and characterized highly wear-resistant polytetrafluoroethylene (PTFE) composites that can be used in tribological applications.

PTFE is gaining importance in sliding and rolling applications in due to its low coefficient of friction, chemically inert behavior (= not reacting with other chemicals), self-lubricating nature, and high stability at varying temperatures.

The self-lubricating nature makes it possible to design systems without external lubrication. This simplifies construction and reduces operational and maintenance costs.

"The fillers I used make it possible to improve wear resistance by two orders of magnitude, making PTFE a real competitor to polyamide, for example," explains Levente.

"Furthermore, I tried to find out why the fillers used produced a significant wear resistance increase," Levente concludes.

His doctoral research was able to come about thanks to an intensive collaboration between UGent, Laboratorium Soete and the Budapest University of Technology and Economics, Department of Polymer Engineering.
