VM Polymer Everest 35 is a solid ethylene-propylene copolymer available in pellet form. This polymer is principally designed for use in the formulation of multigrade crankcase oils, power transmission fluids and industrial oils. When dissolved in suitable basestocks, it produces a viscosity index improver with excellent shear stability and robust low temperature properties. The table in the dosage section indicates the approximate concentrations of VM Polymer Everest 35 Polymer Everest 35 needed to prepare typical multigrade oils.
