- Can meet requirements of high-VI hydraulic oils
- Lowers pour point for enhanced cold-temperature properties
Problems Solved
Multigrade hydraulic oils can be exposed to wide temperature ranges, which affect viscosity and performance. Viscosity modifiers are added to hydraulic oil formulations to improve the viscosity index, but many viscosity modifiers are susceptible to shearing in high-speed applications. Formulators also consider low-temperature properties, as mineral oils are prone to gelling or solidifying in freezing climates.
