G6500V Polymethacrylate Viscosity Index Improver
Product introduction
This product is the solvent of polymethacrylate in the deep refined mineral oil.It is specially designed for long-span vehicle gear oil and internal combustion engine oil, transmission oil, CVTF, automatic transmission oil ATF as viscosity index improver with high shear stability. It is easily soluble in all mineral oils and synthetic base oils and has good compatibility with other traditional lubricating oil additives.
Product Performance:
G6500V has narrow MWD, with excellent performance of shear stability/low temperature/pour-point depressing/viscosity improving, effectively inhibiting the wax crystallization, and meeting new GB standards’ requirement.
