Product Description
SINOPEC 4632 (VG 46/68) Ester-base Fire Resistant Hydraulic Fluid was designed to replace anti-wear, mineral oil-based hydraulic fluids used in applications where fire hazards exist. It can also be used in environmentally sensitive hydraulic applications without compromising the overall hydraulic system operations. This fluid is based on high-quality, synthetic, organic esters and carefully selected additives to achieve excellent hydraulic fluid performance.
Applications
SINOPEC 4632 (VG 46/68) Ester-base Fire Resistant Hydraulic Fluid is suitable for use in:
- Hydraulic applications where there is a risk of fire or 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 fire-resistant anti-wear hydraulic fluid of type ISO 6743/4 HFDU or ISO 12922 is required.
Features and benefits
-
- High flash point (>280°C) and fire point (>330°C) make the fluid resistant to fire, offering a safer working environment and greater equipment protection.
- Excellent storage stability and long product life - comparable to conventional mineral oil fluids or water glycol fluids.
- Readily biodegradable and non-toxic to aquatic life, suitable in applications where there is possible of accidental spillage or leakage of fluid.
- Non-toxic, non-irritating and contains no hazardous ingredients, so safe to use and handle.
- Suitable for use in hydraulic systems operating at a constant pressure of <40 MPa.
- Wide operating temperatures range: from -20°C to 90°C.
- Compatible with iron, steel, and most non-ferrous metals and their alloys.
- Excellent lubrication performance, provided by the polyol ester fluid, protect hydraulic components from wear.
- High viscosity index (VI > 180) provides outstanding viscosity-temperature performance compared to conventional mineral oil (VI ~ 100) and phosphate ester (VI < 0) hydraulic fluids.
- High shear stability means the fluid stays in grade and is not broken down in service.
- Excellent thermal and oxidation stability reduce the formation of deposits and sludge and prevent valve sticking, ensuring longer system life and extended drain intervals.
- Excellent anti-wear performance in hydraulic pumps and valves when used in accordance with the equipment manufacturers' recommendations.
