Napthenic Base Stock

Naphthenic Base Oils or Alkylated Naphthalene’s are Group V base oils made from distillates of crude-oil and are useful in formulating high performance synthetic lubricants.

Excellent Thermal and Oxidative Stability

The aromatic framework connected to long chain alkyl-groups provides favourable properties such as additive solubility, low volatility, seal compatibility and excellent thermal and oxidative stability relative to mineral base oils.

They also have lower pour points than conventional mineral oils due to the lower paraffin content.
