<p>A non-toxic biodegradable grease for lubricating mechanisms, which are exposed to high load such as curving rails in railways and wheel flanges on railway cars and locomotives, as well as for lubricating all sorts of equipment working in areas where full biodegradability is required such as in agriculture, forestry, sports areas and marine environments, comprises a glyceride oil, one or more stearates, one or more long chain esters, bentonite, and a meal. Where the grease is exposed to daylight, it usually further comprises an anti-oxidant, and to further enhance the lubricating capacity of the grease a small amount of polytetrafluoroethylene (PTFE) may be added.</p> |
