Renewable Lubricants said the Bio-Ultimax 1000, a biosynthetic formula that directly replaces mineral oil-based hydraulic fluids, has a flash point of 230° C. The flashpoint of traditional hydraulic fluid is 115°.

Bio-Ultimax 1000 is also safer to handle and is more environmentally friendly. Non-toxic, zinc-free formulations contain no heavy metals.

The formula outperforms traditional hydraulic fluids, the company said. “Ideal for stationary or mobile environments, these super-high Viscosity Index fluids are proven in systems up to 10,000 psi and in systems with ultra-fine filtration.” It is “formulated to perform in high- and low-pressure hydraulic systems that require anti-wear, anti-rust, anti-oxidation, anti-foam, and demulisibility properties.”

Bio-Ultimax 1000 is available in various weights including ISO 32, 46, 68 and 100.
