HYDRAULIC FLUID is a complex combination of hydrocarbons obtained by treating a petroleum fraction with hydrogen in the presence of a catalyst. It consists of hydrocarbons having carbon numbers predominantly in the range of C20 through C50 and produces a finished oil of at least 100 SUS at 100.degree.F (19cSt at 40.degree.C). It contains a relatively large proportion of saturated hydrocarbons.
Flammability and Explosibility
Non flammable
Confirmed carcinogen.
Low toxicity by ingestion and skin contact.
When heated to decomposition it emits
acrid smoke and irritating fumes.
The ITSL for hydrotreated heavy paraffmic mineral oil is 50 μg/m3 based on a 8-hour averaging time.
