MK-6510V Polymethacrylate (PMA) Viscosity Index Improvers for Hydraulic Oil
Boasting excellent performance in improving VI, outstanding low-temperature performance and good shear stability, PAMA viscosity index improvers are widely used in HV (VIz140) hydraulic oil or those needing a better VI. Given the different shear stability requirements depending on the OEM or industry specifications for oils, PMA viscosity index improvers, thanks to their flexible molecular design, can be developed into a whole series of products with varied molecular weights and other structural parameters to meet the actual needs.
