CITGO Glycol FR-5046HP is a high pressure polymer thickened water-glycol fluid which provides superior fire-resistance at pressures in excess of 5,000 psi. Pump test results (see Tables 1, 2 and 3) show CITGO Glycol FR-5046HP low pump wear rates to be essentially equivalent or significantly better than phosphate esters and polyol esters. CITGO Glycol FR-5046HP, therefore, provides long pump life at high pressures, excellent fire safety plus lower cost than synthetic fluids. Application include mobile equipment or stationary hydraulic systems in steel mills, foundries, die casting, power transmission plants, etc. It can also be used in equipment operating in environmentally sensitive areas. The FR-5046HP product has been shown to have a lower environmental impact than mineral oil based products. Testing of the fluid has shown that it is relatively harmless to the aquatic species commonly tested in the U.S. and Canada, additional testing has also shown that FR-5046HP is relatively harmless to terrestrial species such as earthworms and plant seedlings. CITGO Glycol FR-5046HP is readily biodegradable per OECD 301B.
