Viscosity Index Improvers for Hydraulic Oil of Polymethacrylate

MK-6530V Polymethacrylate (PMA) Viscosity Index Improvers for Hydraulic Oil

MK-6530V Hydraulic Oil Viscosity Index Improvers is a solution of modified polymethacrylate (PMA) in deeply refined mineral oil. Mainly used in top-grade low temperature hydraulic fluids with low pour point and high viscosity index, it can both improve the viscosity index and depress the pour point while ensuring the shear stability. Serving an important role in high-performance hydraulic fluids, it can effectively improve the viscosity index and the low-temperature performance of the oil and also provides outstanding filtering and anti-emulsifying functions.

Suggested Use

Add 1.0%~20.0%wt to the specified base oils. To determine the exact amount of MK-6530V functional polymer required, we need to test the blended oil’s base oil types, thickening property, viscosity index, and pour point.
