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
Higher pour point.
Higher viscosity index.
Low volatility and, consequently, high
Low specific gravities.
