New biodegradable lubricant

A new biodegradable lubricant(s) especially developed for mobile hydraulic systems equipped with low friction DLC coatings has been developed. New lubricant provides a good lubrication of classic hydraulic systems and systems with DLC coatings as well. It is ready biodegradable and non-toxic. Its lifetime is be comparable with mineral oil. Therefore one unsaturated ester and one complex-saturated ester with appropriate additives have satisfied all technical demands. All base stocks (base oils and additives) are current state of the art in the field of biodegradable lubricants. Of course some structural changes are expected to conform lubricant with DLC coatings.

New lubricant is primarily intended for mobile hydraulic systems with DLC coatings in tractors, forestry equipment, construction equipment, agricultural equipment, where problems with soil and water pollution with oil can occur. The market potential is also non DLC hydraulic systems because its very high oxidation stability and biodegradability. New lubricant(s) is also foreseen for lubrication of some parts of grinding machines coated with DLC. The current biodegradable hydraulic oil market size in EU is round 67.000T/year. The potential of a new lubricant is strongly focussed on first fill of project's end users. So far the estimated price of the product will be in the range of other market biodegradable synthetic oils. Total fraction of bio lubes in EU is still very little. Draw backs are high price and shorter change interval.

The environmentally (biodegradability, non-toxicity) and technical (DLC compatibility) aspects are strongly emphasised by development of new lubricant.
