SKF Ecoflon 2 is a polytetrafluoroethylene filled with glass fibres and molybdenum disulphide (PTFE with fillers) and can be used for U-cups, glide rings, back-up rings, packings and guide rings. SKF Ecoflon 2 has good physical properties and significantly better creeping behaviour than virgin PTFE. The chemical resistance is similar to virgin PTFE.
