Fire Retardant Chemical (Organic Ester)


FIRESAFE HFDU 68 is an ester-based, high-performance and fire hydraulic fluid.

FIRESAFE HFDU 68 is designed for hydraulic equipments operating  in locations comprising a fire risk, such as iron and steelworks (coking plants, blast furnaces, continuous casting), mines, etc... The use of FIRESAFEHFDU 68 lessens the serious risks presented by recourse to a mineral oil on the occasion of rupture of a hose or when a leak gives rise to oil mist, in the immediate vicinity of a flame, a part in the process of melting or a switch cupboard.

FIRESAFE HFDU 68 is especially recommended when there is the possibility of contamination of waters : offshore, mines.

With its considerable fire resistance properties, and associated exceptional lubricating properties which guarantee a substantial reduction in wear and therefore a longer service life of the hydraulic components.

High flash point and high auto ignition temperature. Low pour-point providing good performances at low temperature.

Very high natural viscosity index, guaranteeing a viscosity constantly adapted to the temperature range in which the fluid must be used.

Very good anticorrosion properties in relation to ferrous and non-ferrous metals making up a hydraulic circuit.

Very good oxidation stability: enhanced service life. The product is not expected to produce adverse effects on health.
