1. Product Introduction & Main Application
Arnico’s Base Oil SN 90 is a light-viscosity, paraffinic Group I mineral base oil, obtained from the solvent refining of lube oil cuts of crude oil. This light base oil is the primary raw material for the production of cold-climate engine oils, light industrial hydraulic oils, rubber process oils, and high-speed turbine oils.
