Naphthenic Base Oils - Refined from sweet crude oil distillates. Naphthenic base oils have a very low
aromatic content and a low paraffin (Wax) content. These characteristics allow for a low pour point on lighter viscosities and a
high degree of solvency where heavier viscosities are required.

Naphthenic oil is a reasonable choice for the following special properties:
1. High solubility
2. Excellent low temperature performance
3. Excellent compatibility with some resins and polymers
4. Good plasticization and mutual solubility with rubber
Typical application markets of naphthenic base oil are:
1. Transformer oil, which provides cooling and electrical insulation performance;
2. Process oil, which is used in a large number of chemical processes to provide excellent solubility;
3. Lubricating oil, which is used to produce metalworking fluids, grease and industrial oil.
4. Rubber filling oil: A variety of rubber can be used as plasticizer and filling oil to improve the plasticity and elasticity of rubber.
