Polytetrafluoroethylene and nylon
Thread Content
I would like to ask the experts: what is the difference in wear resistance between polytetrafluoroethylene and nylon? Previously, the sliders on the device were made of PTFE material; to save costs, they were replaced with nylon material, and there are concerns about how long they will last.

After doing a search on Baidu, the description of nylon mentions that \"polyamides are mainly used in synthetic fibers, and their most notable advantage is their higher wear resistance compared to all other fibers.\" However, PTFE has a lower friction coefficient, so it should exert less resistance. Overall, it is estimated that PTFE will still be used for a longer period of time; the exact difference depends on practical experience. If you have come to any conclusions, feel free to share them~ For reference: The English name for polyamide/polytetrafluoroethylene blends is polyamide/polytetrafluoro-ethylene blend, abbreviated as PA/PTFE. Modifying PA with PTFE can improve its wear resistance and reduce the friction coefficient. Taking nylon 66 as an example, by adding 20% PTFE, the wear coefficient is reduced to 1/16, the friction coefficient is decreased by about half, and the critical pV value increases by 10 to 20 times”
