ESTER-BASED FIRE-RESISTANT HYDRAULIC FLUID (ISO VISCOSITY GRADES: 32, 46, 68 AND 100)

Supplier of Ester-based Fire-resistant Hydraulic Fluid 4632 is a range of polyolester type hydraulic fluids formulated with selected additives, available in four ISO viscosity grades: 32, 46, 68 and 100. This biodegradable and environmentally responsible fluid, which does not contain water, mineral oil or phosphate esters, can be used in place of a conventional anti-wear hydraulic fluid in applications where there is a risk of fi re or accidental environmental contamination, where it achieves excellent hydraulic fluid performance.

SINOPEC ESTER-BASED FIRE-RESISTANT HYDRAULIC FLUID 4362 (ISO VISCOSITY GRADES: 32, 46, 68 AND 100)

FEATURES AND BENEFITS

High flash point (270°C) and fi re point (330°C) make the fluid resistant to fi re, offering a safer working environment and greater equipment protection. Excellent anti-wear performance in hydraulic pumps and valves when used in accordance with the equipment manufacturers’ recommendations. Excellent thermal and oxidation stability reduce the formation of deposits and sludge and prevent valve sticking, ensuring longer system life and extended drain intervals. High shear stability means the fluid stays in grade and is not broken down in service. Very high viscosity index (VI > 180) provides outstanding viscosity temperature performance compared to conventional mineral oil (VI ~ 100) and phosphate ester (VI < 0) hydraulic fluids. Good lubricity properties provided by the polyolester fluid protect hydraulic components from wear. Compatible with iron, steel and most non-ferrous metals and their alloys. Wide operating temperatures range from –20°C to 90°C. Suitable for use in hydraulic systems operating at a constant pressure of >40 MPa. Non-toxic, non-irritating and contains no hazardous ingredients, safe to use and handle. Readily biodegradable and non-toxic to aquatic life, suitable in applications where accidental spillage or leakage of fluid is possible. Excellent storage stability and long product life comparable to conventional mineral oil fluids or polyglycols.

RECOMMENDED APPLICATIONS

• Hydraulic applications where there is a risk of fi re or of accidental environmental contamination, where a conventional mineral oil based anti-wear hydraulic fluid would present a fire hazard or pollution hazard.

• Hydraulic applications where a fi re-resistant anti-wear hydraulic fluid of type ISO 6743/4 HFDU or ISO/FDIS 12922 is required.
