Polyol ES Base HF Series

Product Description

They are polyol ester-based, highly fire resistant environmental-friendly hydraulic fluids which do not contain any mineral oil.

Application/Usage

They are fire resistant hydraulic fluids and can work under very difficult conditions. Mineral oils can not be used in processes where casting, furnaces and liquid metal are present such as hydraulic die-casting and chilled casting machines, automatic injection molding machines, hydraulic forging presses, machines in the mining industry. Under such conditions, utilization of fire resistant hydraulic fluids is necessary. 

In high pressure hydraulic systems, small fractures may cause the fluid splash and the spontaneous ignition temperature of mineral oils is about 350 °C, which means that above this temperature threshold such mineral oils ignite without being exposed to a naked flame. The flame continues to spread through the source; burning mineral oil does not even go out when the actual source of ignition has been eliminated. These dangers are avoided by using a fire resistant hydraulic fluid.
