  • Product Description
  • | Product Overview

    G6800V is a synthetic polymethyl methacrylate‑based multifunctional viscosity index improver that does not compromise the high affinity of polar base oils for metal surfaces, ensuring that the lubricant film remains intact even under heavy loads. With excellent oxidation resistance and exceptional chemical stability, this copolymer exhibits outstanding solubility in a wide range of mineral and synthetic oils. By modifying the original polymerization structure of polymethyl methacrylate and incorporating a comb‑like architecture, it delivers superior shear stability. In internal‑combustion engine oils, it can significantly reduce overall fuel consumption by 3–4%, in line with increasingly stringent fuel‑efficiency and emission standards.

     

    | Product Performance

    Suitable for reducing wear in internal combustion engines, transmission gearboxes, clutches, or pumps.

    Wear-resistant

    It exhibits high antioxidant and thermal stability, as well as excellent shear strength.

    It improves the fluidity of lubricating oil.

    It has a viscosity index improving effect.

    It exhibits high solubility and, in non-polar lubricants—such as fully synthetic oils—can dissolve in large quantities.

    It exhibits viscosity index improvement, dispersancy, detergency, and pour point depression.
