Meldin® 7211 has 10% PTFE and 15% graphite filler, which provides the lowest coefficient of friction of the 7000 series polyimides.
this material is an excellent high-temperature, high PV bearing material in dry service.
Above 300°F we recommend using Meldin® 7021 instead, which has a very similar coefficient of friction to 7211 with a lower wear factor at those temperatures.
