Product Introduction
JDVII6051 is a solution of poly(methyl methacrylate) in deeply refined mineral oil. It is a high shear stable viscosity index improver specially designed for large-span vehicle gear oil.On the premise of ensuring shear stability, it has the dual effects of increasing the viscosity index and reducing condensation, effectively saving product formulation costs.
Product Performance
Narrow molecular weight distribution and excellent shear stability,
Excellent low-temperature performance, can effectively inhibit the crystallization of wax, and has excellent pour point reduction effect on base oils of different viscosities.
