Naphthenic Oil

Introduction of Naphthenic Oil :

In contrast to paraffinic oil, naphthenic oil are distinguished by a molecular structure composed of "rings" of hydrocarbons, i.e., the hydrogen and carbon atoms are linked in a circular pattern. Naphthenic oil do not contain wax and behave differently than paraffinic oils. Naphthenic Oil have very good solvency with low pour points. They also have good color stability. Naphthenic oil have lower flash points than corresponding paraffinic oil Naphthenic Oil have:

 

 

• Good stability.
• Lower pour point due to absence of wax.
• Lower viscosity indexes.
• Higher volatility (lower flash point).
• Higher specific gravities.

 

Application of Naphthenic Oil :
Naphthenic Oil are generally reserved for applications with narrow temperature ranges and where a low pour point is required, e.g. refrigeration compressors and other special applications
