This product is a solution of polymethacrylate in a highly refined mineral oil. It is a viscosity index improver specially designed for long span vehicle gear oil with high shear stability.
With narrow molecular weight distribution and excellent shear stability, it can meet the requirements of the new national standard. Excellent low temperature performance, can effectively inhibit wax crystallization, for different viscosity of the base oil has an excellent pour point effect.
It is suitable for the modulation of long-span vehicle gear oil, and can effectively improve the viscosity index of the oil. Under the premise of ensuring the shear stability, it has the double effects of improving the viscosity index and reducing the pour point, and effectively saves the formula cost of the product.
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 determined.
Main physical and chemical indexes of SCR-9050 viscosity index improver are shown in Table 1
