GALX-8615 PPD-Type Viscosity Index Improver OCP Ethylene-Propylene Copolymer Description GALX-8615 has good shear resistance, thickening ability, excellent cryogenic pumping performance and good effect of depressing pour points. It is suitable for high-grade internal combustion engine oils, and can also be used in gear oils and metalworking oils as auxiliary thickeners. GALX-8615 can be used for the production of multigrade internal combustion engine oils, which can meet the requirements of API CI-4, CH-4, CF-4 grades. The oils blended with GALX-8615 has good low-temperature flow performance, and have a good effect of depressing pour points on the oils with higher than 15W grade without adding other PPD. GALX-8615 can also be used as energy-saving additive of engine oils as VII.
