Product Description

Product Description

Viscosity Index Improver T7700 is an HSD-type viscosity index improver (VII). It features strong thickening ability, good low-temperature performance as well as good shear stability. It effectively improves lubricants' viscosity-temperature character and viscosity index.
T7700 is in the form of power or fluffy particles with low dissolving temperature and fast dissolving rate.

Chemical Composition: Hydro Styrene-vinyl Diene Copolymer

Application

It is a high-end viscosity improver, widely used to blend  multi-class Internal  Combustion Engine (ICE) oil, especially in the production of large-span multi-class engine oil.
