PMA Polymethacrylate Lube Additive Viscosity Index Improver is a kind of the efficient viscosity index improver, and it can availably improve the viscosity index. The product is transparently sticky liquid, and the dosage has no effect on the transparence of the oils. Viscosity index improver is belong to one of Lubricant Additive Component and it's generally oil soluble chain mersmacromolecular compound. The main purpose is to improve the viscosity temperature performance and increase the viscosity index of lubricatnt oil, shear stability and thickening ability are the main indexes to evaluate the viscosity index improver.
Lubricant Additive Viscosity Index Improver has the main composition of polyalkyl methacrylate polymer with the appearance of light transparent viscous liquid. The outstanding performance of reliable shear stability and high & low temperature stability, ect. It can be used for formulating many kinds of the oils such as gear oils, special hydraulic oils and internal-combustion engine oils and so on. It can mixed with Pour Point Depressant or other kinds of lube additive to made Additive Package.
