Group-I Base Oil
TNZ–SN 350 is known as a middle grade base oil. This high viscosity index base oil is mostly used in lubricant production. It is a group I base oil which has undergone solvent refining processes. To finish the refining, it was hydrogen treated to clear out any impurities. TNZ–SN 350 has a good lubricity and is suitable as a base oil for formulation of transmission fluids, gear oils, metal working fluids and hydraulic fluids.
