PMA viscosity index improver SCR-9138


一、Product Introduction

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.


二、Product Performance

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.


三、Product Usage

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.

Main physical and chemical indexes of SCR-9138 viscosity index improver are shown in Table 1
