GALX-8615 PPD-Type OCP SAE 0W/10W Engine Oil Viscosity Index Improver
Ethylene-Propylene Copolymer
CAS:9010-79-1
Description
GALX-8615 has good shear resistance, thickening ability, exnt 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 for higher than 15W grade without adding other PPD. GALX-8615 can also be used as energy-saving additive of engine oils as VII.
Key performance Benefits
Exnt shear stability
Less carbon deposition
Exnt low-temperature performance
