Low temperature properties of hydraulic fluids - design tools available for the formulator

摘要

Hydraulic fluids are utilized under varying ambient conditions. Globally, there are clear regional demand differences. In the Northern hemisphere, a robust demand for low-temperature adapted lubricants, e.g. in the Arctic regions of Eurasia and America, for outdoor applications during the long winter season, . High performance lubricants are required in hydraulic systems; and can deliver reliable service even under harsh conditions. The challenge for the Lubricant Formulator is how to create a lubricant solution with an attractive price/ performance ratio, and with favourable Theological properties. Some important aspects are long-term storage stability, and ease of start-up properties of the hydraulic systems.
