Duratherm 450 FG Heat Transfer Fluid
Categories:	Fluid
Material Notes:	Duratherm 450FG is specifically engineered for applications requiring a food grade thermal fluid for process heating and cooling precisely and efficiently between -25°C and 232°C (-12°F and 450°F). Duratherm 450FG is ideal for low temperature applications such as blow molding, injection molding, pharmaceutical manufacturing or any application requiring batch heating and cooling. The exclusive additive package, including a proprietary dual stage anti-oxidant, ensures long trouble free operation. Duratherm 450FG also incorporates metal deactivators, a seal and gasket extender, de-foaming and particle suspension agents. Duratherm is engineered to give unsurpassed levels of oxidation protection and service life. Duratherm 450FG is environmentally friendly, non-toxic, non-hazardous and non-reportable. After its long service life it can easily be disposed of with other waste oils. Information provided by Duratherm.
