This high wear rate limits the use of PTFE as a bulk solid lubricant. The high wear rate and the wear mechanisms of PTFE also leads to large, flakey wear debris, which can also be very disadvantageous. Low wear rates have been observed in PTFE at low contact pressures and sliding speeds [17, 34]. However, under typical engineering sliding ...
applications. Unfortunately, PTFE suffers from poor wear resistance [2]. efforts. More specifically, the use of orthogonal Arrays (Because of the relative softness of PTFE, it is logical to expect that its load-carrying ability and its wear resistance might be improved by the addition of suitable fillers.

3. UHMW has higher abrasion resistance than PTFE. Both have great impact and wear resistance but because of UHMW having a molecular weight between 2-6 million making it the best wear resistance material in the plastic family, it makes it ideal to take wear and impact over a wider range and longer period of time without losing its properties. 4.

provided a collective effect that increased the wear life of PTFE films by more than 940 times. Because of the relatively low thickness of the film, it shows great potential for use in applications where durable, thin films are desirable.
suggest that the wear reduction mechanism is largely due to a mechanical effect of the nanoparticles. In direct contrast, however, a 2005 study by Burris and Sawyer revealed the first evidence of a nanoscale-specific wear resistance mechanism; alumina-PTFE was more than 100× more wear resistant than prior nanocompos-

Where performance is a key criterion, the correct material choice to meet the requirements of an appli-cation is of prime importance. Since there is a wide
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. The commonly known brand name of PTFE-based compositions is Teflon by Chemours, a spin-off from DuPont, which originally discovered the compound in 1938.. Polytetrafluoroethylene is a fluorocarbon solid (at room temperature), as it is a high-molecular-weight polymer consisting ...
PTFE chemical- and wear-resistant tubes have a naturally slippery surface with high-bulk resistivity that makes them suited for fabricating the electrostatic analogues of magnets. PTFE resists chemicals, performs well in extreme temperatures, and is an excellent electrical insulator.
This dissertation presents an investigation into the effect of nanoparticle fillers and a polydopamine adhesive primer on the tribological performance of thin PTFE films. The principal objective of this investigation was to reduce wear in PTFE films, an issue which precludes the use of PTFE films in tribological applications requiring high durability.
Filled PTFE Wear Rings are typically used in cylinders and machinery with requirements for dynamic performance and service life. PTFE materials are well known for their low friction, heat resistance, wide temperature range performance, high chemical resistance and excellent wear characteristics.
