Hydraulic fluids

PCC Group products covers raw materials for specialised fire-resistant hydraulic fluids and also AW additives for all types:

• Base stocks for HFDU type hydraulic oils – polyalkylene glycols
• Base stocks for HFDR type hydraulic oils – triaryl phosphate esters
• Emulsifiers for HFA-E type hydraulic oils – C16-C18 alcohol, alkoxylates
• EP & CI additives for HFA-E & HFC hydraulic oils
• AW additives for mineral, synthetic & HFDU hydraulic oils – triaryl phosphate esters

HFDU are non-aqueous products based on PAGs. Could be based on mineral oil soluble, water insoluble PAGs or water-soluble PAGs. All base stocks can be designed to be readily biodegradable, non- -toxic and non-hazardous. Generally are non-hazardous when burned. Recommended operational temperature is from -20°C up to +70°C.

HFDR are non-aqueous products based on neutral phosphate esters. Generally they have environmental and health impact but could be designed to reduce those effects. Generally impossible to ignite and flame. Recommended operational temperature is from -20°C up to +70°C.

HFA-E are aqueous products based on over 95% of water, mineral oils, emulsifiers and additives. Can be designed to be readily biodegradable, non-toxic and non-hazardous. Generally simply impossible to ignite and flame. Recommended operational temperature is from +5°C up to +50°C.

HFC are aqueous products designed as water-polymer solutions. Usually contain about 40% of water. Generally they could have environmental and health impact but could be also designed to reduce those effects. Depends on ingredients could be hazardous when burned. Recommended operational temperature is from -20°C up to +50°C.
