This product is a solution of polymethacrylate in a highly refined mineral oil. It is a viscosity index improver with high shear stability specially designed for transmission oil production and blending.
With narrow molecular weight distribution and excellent shear stability, it can meet the shearing requirements of oil products under harsh conditions. Excellent low temperature performance, can effectively inhibit wax crystallization, for low viscosity base oil has an excellent depressant effect.
Suitable for the modulation of transmission oil, and can effectively improve the viscosity index of oil, under the premise of ensuring shear stability, it has the double effect of improving the viscosity index and reducing the pour point, and effectively save the product formula cost.
四、Evaluation of viscosity index improver
The evaluation is carried out according to SH/T0622-2007 standard.
The kinematic viscosity, flash point and thickening ability of the viscosity index improver are measured.
