Base Oil SN150 Definition

Base oil SN150 is known as a light grade base oil at the lower end of the specifications for Grade I light base oils. It is mostly used in lubricant and lubricant additives production. It is a Group I base oil which has undergone solvent refining processes. To finish the refining it was hydrogen treated to clear out any impurities.

Base oil is referred to as a base for lubricants. The most important constituent of the volume of lubricants is base oil and, on average, constitutes more than 1% of the formulation of a lubricant. In some lubricants (compressor and hydraulic oil) 2% of the oil is base oil and only 2% is additives. Base oils can be obtained from petroleum or non-oil sources. Most of the world’s base oils come from crude oil refining. The major constituents of base oils are paraffinic, naphthenic and aromatic compounds.

Chemical properties of base oil and how it affects the performance of the final lubricant

  1. Volatile: Oil depletion, oil thickening and sediment formation.
  2. Surface activity: foaming, air release, emulsion formation and pressure.
  3. Oxidation: Formation of sediments, oil concentration, sludge formation and corrosion of metals.
  4. Viscosity: Low temperature fluidity, energy loss, wear protection and proper cooling.
  5. Solvent power: engine cleanup, sealant compatibility, process applications and formulation stability.

Applications

  1. General purpose oils
  2. Mould oil
  3. Transmission fluids
  4. Gear oils
  5. Metal working fluids
  6. Additives
  7. Hydraulic oils
  8. Transformer oils
