Synthetic Ester Base Oil for Biodegradable Difficult-flammble Hydraulic Fluid(HFDU)

Description

Ester base oil series for difficult-flammble hydraulic oils are refined through the special-technique treatment process after the reaction between neo-polyhydric alcohol and long carbon chain unsaturated fatty acid or diacid. It is especially suitable for HFDU) and biodegradable HEES hydraulic oils.

These ester series have good fire-resistance performance, meeting the industry standards for the special needed applications including fire-resistant hydraulic oils and processing industry, which can reduce the abrasions and prolong the service life of tools/rolling wheel and improve the surface smoothness so that the cost of reprocessing workpieces can be reduced.

It can be safely used in pure-oil cutting, especially for the high requirements of generating heat, maximum lubricity, prolonging the service life and improving surface smoothness.

It can be used in alkaline water-based products without going bad, maintaining its lubricity. It has no bad influence for physical forms and performances of the tools in a variety of hot and cold climate conditions.

Key performance benefits

√ High flash point

√ High ignition point

√ Good fire-resistance performance, reducing the flaming possibility when contacting with hot metal, electric spark and flame or encountering the rupture of hydraulic oil circuit or oil leakage.

√ Safe use with high biodegradability with more than 90% rate of these esters tested by (ECL-3) _T82

√ High viscosity index and wide service temperature

√ Good corrosion and rust resistance, excellent lubrication performance

√ Excellent thermal stability, prolonging the oil change period

√ Without releasing toxic gas when contacting the tool surface at high temperatures

√ Excellent emulsification and foam resistance

Biodegradable, no pollution to the environment.
