MK-6500V 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.
