Abstract:
A wear and friction article, including on at least one of the surfaces thereof a polymeric material comprising: 20 to 100% by weight of at least one polyetherketoneketone (PEKK); 0 to 80% by weight of one or more fillers; and 0 to 20% by weight of one or more additives. Also, the use of such a polymeric material for reducing wear and/or friction at elevated temperature.
