G6800V Polymethacrylate viscosity improver


G6800V is a synthetic polymethacrylate multifunctional viscosity index improver  that does not impair the high affinity of polar base oils to metal surfaces and keeps the lubricant film intact under high loads.Highly antioxidant and chemically stable, the copolymer has excellent solubility in many different mineral or synthetic oils.This polymer changes the polymerization structure of the original POLYmethacrylate, introduces comb products for polymerization, shear resistance, based on higher fuel efficiency and emission standards, the injection of I into the internal combustion engine oil will significantly reduce the system fuel consumption by 3-4%.


Product performance

Copolymers are designed to reduce wear in internal combustion engines, transmission gearboxes, clutches, or pumps

- Protection against wear.

- High anti-oxidation and thermal load stability, as well as high shear strength.

- Improving lubricant fluidity.

- Improving viscosity index.

. Highly intermiscibility, soluble in nonpolar lubricants, e.g. in large quantities in fully synthetic oils

- With performance of the viscosity index improvement , the clean dispersion , the detergency, the pour point reduction.
