Overview:
Synthetic ester-based fire-resistant hydraulic oil is a high-performance oil for hydraulic systems developed by adopting advanced synthetic ester technology. It is meticulously formulated to meet the dual requirements of lubrication and safety guarantee for hydraulic equipment under severe working conditions such as high temperature, high pressure and high fire risk.
Performance Features:
Good material adaptability, with lower requirements for sealing materials than phosphate ester-based fire-resistant fluids.
It has a low pour point, a high flash point and a high viscosity index, and features a wide application temperature range.
It boasts excellent lubricating performance and anti-shear stability.
It has outstanding thermal stability and a long service life.
It has excellent anti-foaming and anti-emulsifying properties.
It is easily biodegradable and environmentally friendly.

This product is applicable to the hydraulic systems of continuous casting production lines operating under harsh conditions, as well as the hydraulic systems of equipment that require fire resistance and safety, such as blast furnaces, furnace dismantling machines, hot rolling mills, foundries, ladle valves, power stations and coal mines.
The operating temperature range is from -30ºC to 150ºC, and the operating pressure can reach up to 30Mpa.
