The most important role of a hydraulic fluid is transmission of power among various roles. A bulk modulus of the fluid is crucial for hydraulic systems, particularly for high-pressure hydraulics. In theory, compression energy losses are in diverse proportional to the effective bulk modulus of the fluid, and response speed and stability depend directly on the square root of it. Conventional mineral oils have pretty low bulk modulus, compared to water-based hydraulic fluid. On the other hand, the water-based fluids are disadvantageous in lubricity and evaporation. Under the circumstances, we've searched for available oily high bulk modulus fluid, and found organic compounds with water-level bulk modulus.
