AD-8620HT OCP Viscosity Index Improver with High Anti-shear Ability
Description
AD-8620HT belongs to OCP (Ethylene-propylene Copolymer ) series which has excellent shear resistance.
AD-8620HT not only has excellent anti-shear ability and good low-temperature performance of high-viscosity Poly a Olefin(PAO), but overcome the bad compatibility of Poly a Olefin combined with additives. It also has good stickiness of PIB, which is good for the lubrication of high-speed gears.
AD-8620HT has extremely advantages when used in low viscosity and large-span viscosity of engine oils (such as 0W16, 5W20, 5W40). When used in high-speed gear oils, it has excellent low-temperature performance and strong thickening ability.
