Hello and welcome to a new post in which we are looking for a smarter way to reduce friction and wear in engineering plastics—without relying on PTFE.
Replacement of PTFE with UHMW-PE - How much should I add?
Ultra-High-Molecular-Wheigt-Polyethelyne (UHMW-PE) stands out as a highly effective alternative to PTFE and molybdenum disulfide, especially when high temperatures are not a concern for your final application. Discover how this innovative approach can boost performance and open new possibilities for your polymer selection and engineering plastics projects.
Table 1 shows how adding just 5 wt% of UHMW-PE to materials like PA 6 can dramatically lower the kinetic friction coefficient from 0.6 to 0.23. Similar improvements are possible with PBT (from 0.51 to 0.2) and PPS (from 0.38 to 0.14)!
