In a study entitled "Blends: Friends or Foes?" Nynas researchers argue that the lubrication industry has a lot to gain from promoting base oil blends for grease formulations.
Blends offer the opportunity to turn the disadvantages of the current surplus of Group II and Group III oils into an advantage. Nynas researchers found that by blending these with naphthenic oil, the two main drawbacks of Group II and III base stock – reduced solvency or solvent power, and a lack of high viscosity oil grades – can be overcome easily. In their study, they produced three lithium-based greases by blending Group I, II and III oil with naphthenic oil. All three greases displayed good results in a number of tests. The lubricating grease based on the blend of paraffinic Group II and naphthenic oil performed particularly well.
As usual, Nynas will have a strong presence at the STLE Annual Meeting, presenting three different technical papers.Read more about The premier event for tribology research and lubrication engineering
The International Maritime Organization (IMO) has announced that it will dramatically lower the global limit on sulfur content for marine fuels from the current 3.5% to 0.5% as of 2020. The aim is to significantly curb pollution produced by the world's ships. Three experts reflect on what this means.Read more about The impact of IMO 2020
