Product Description

Product Description

T602HB is a polymethacrylate (PMA) viscosity index improver that is well-suited for use in low-viscosity engine oil, long-span gear oil, low-temperature hydraulic oil, and other lubricating oils. This product has viscosity index-improving performance, along with a pour-point depressing effect that makes it particularly useful in cold climates.
By adding T602HB to your lubricating oils, you can effectively increase the viscosity index and improve the low-temperature performance of the oil. This product has been specifically designed to deliver exceptional performance and a powerful viscosity index improvement capability.

General Description

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.

Methacrylic acid 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:
