G6805V Polymethacrylate Viscosity Index Improver
Product introduction
Product performance
It is recommended for blending automatic transmission fluid at 6 speeds and above as well as CVT continuously variable transmission fluid.
This product has a narrow molecular weight distribution, excellent shear stability, and can improve the viscosity-temperature performance of oil products. It also has good low-temperature performance and can inhibit wax crystallization.
Effectively disperse impurities, such as soot and carbon deposits produced by the oxidation of oil during use, to extend the service life of the oil.

Note 1: The difference between the 100°C kinematic viscosity of HVIH5 base oil after adding 10% viscosity index agent and the 100°C kinematic viscosity of the base oil.
Note 2: After adding 10% viscosity index to the HVIH5 base oil, measure its shear index.
Note 3: Measure the pour point of HVIH5 base oil after adding 10% viscosity finger agent.
