PMA Viscosity Index Improver
PMA Viscosity Index Improver:
Polymethacrylate (PMA) viscosity index improver is used in the formulation of hydraulic oil (especially low-temp hydraulic oil), gear oil, shock absorber oil, transmission oil and other applications. This product provides excellent shear stability, which effectively improves the viscosity index and low temperature performance of the oil.
