T630V is a polymethacrylate (PMA) viscosity index improver. It is suitable for blending hydraulic oil (especially low-temperature low condensation hydraulic oil), gear oil, shock absorber oil, transmission oil, and other oil products. With excellent shear stability, it can effectively increase the viscosity index and improve the low-temperature performance of oil products.

Polymethacrylate, (PMA) was first developed in the 1950s as a synthetic rubber substitute. In the 1970s, researchers began investigating the use of PMAs as VIIs in lubricants. They found that PMAs had excellent shear stability, good low-temperature performance, and oxidation resistance.
Methacrylicacid is esterified with higher carbon alcohol under acidic conditions to form methacrylate, and the generated water is continuously absorbed by sulfuric acid to make the reaction continue. Remove the unreacted substances and by-products from the crude methacrylate, after refining, carry out free radical polymerization under the trigger of benzoyl peroxide or azobisisobutyronitrile, etc., and also use dodecanethiol to control the molecular weight (in During the polymerization process, a certain amount of diluent oil should be added), the reaction formula is:
