Meldin® 7211 | 10% PTFE & 15% Graphite Filler

Meldin® 7211

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.
