Product Introduction
Oil thickener–HSD Viscosity index improver is a viscosity index improver of polyhydrogenated styrene-isoprene type. It possesses excellent permanent shear stability, outstanding low-temperature flow properties, ideal high-temperature and high-shear performance,and has a good sensitivity to anti-gelling agents.
