Paraffinic Oils Review

Paraffinic oils are distinguished by a molecular structure composed of long chains of hydrocarbons, i.e., the hydrogen and carbon atoms are linked in a long linear series similar to a chain. Paraffinic oils contain paraffin wax and are the most widely used base stock for lubricating oils. In comparison with naphthenic oils, paraffinic oils have:

• Excellent stability (higher resistance to oxidation).
• Higher pour point.
• Higher viscosity index.
• Low volatility and, consequently, high flash points.
• Low specific gravities.
