Etronax MFP G - Sheet

The fabric is cotton in one direction and polyester in the other: the cotton provides strength and good mechanical properties, while the polyester adds wear and slip properties beyond what cotton alone offers, with a mild self-lubricating effect. Used for bearing materials, both large and small bearing bushings.

Etronax MFP G vs. MF

Plain MF/MMF's cotton weave is already wear-resistant and low-friction in its own right. Etronax MFP G replaces some of the weave with polyester threads, which sharpens those properties. The real reason to choose MFP G over plain MF variations is the application rather than a big performance jump: it is used for ball bearing cages and bearing bushings, where a mildly self-lubricating surface is needed rather than a purely dry-running one.
