Base oil SN 650

General features

The product is obtained from the crude oil vacuum fraction, selectively refined out of solvents, dewaxed and hydro-refined. Those processes enable receiving the desired properties of the final product, such as lack of low-index substances, better colour, good low-temperature and thermo-oxidation properties. Base oil SN 650 is intended for use in lubricants production.


Base oils are used for the production of lubricating oils, oil products, greases, plasticizers.
