Base Oil SN650 Definition

Base Oil SN650 is base oil categorized in group I is the common quality base oil product of SHGOC which use in different applications this grade SN 650 is a base oil at the upper end of the specifications for Grade I base oils. They are mainly used in lubricant production. It is a Group I base oil which has undergone solvent refining and de-waxing processes. To finish the refining it is hydrogen treated to clear 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. Engine oils.
  2. Transmission fluids.
  3. Gear oils.
  4. Metal working fluids.
  5. Greases.
  6. Hydraulic oils.
  7. Transformer oils.
