The relatively high density and low viscosity index of naphthenic oils confers superior heat transfer properties, resulting in a more effective cooling of the different machine parts. The superior solvency powers of naphthenic oils help them to dissolve high amounts of performance additives, and keep these in solution.
This high solvency power brings advantages to naphthenic oils in the production of water-based fluids, in terms of formulation flexibility, and once formulated, naphthenic based emulsions are known to be very stable. Here again the high density of naphthenic oils contribute to the stability of emulsions based on them in centralized lubricating systems, where these water-based formulations are less sensitive to the centrifugal forces of the pumps. Nynas offers a wide variety of oils to the metalworking fluids industry that includes naphthenic oils with different refining degrees, so you can always find a product that can adapt to your application within our portfolio.
