Summary (All Propylene Glycol Properties Listed on Product Pages, See Below)

Dowfrost HD™ Inhibited Propylene Glycol heat transfer fluid includes a specially designed package of industrial corrosion inhibitors. Propylene glycol antifreeze solutions have an operating temperature range of -50°F to 325° F (-46° C to 163° C), and the antifreeze is dyed bright yellow in color to aid in leak detection.

In applications where toxicity is a concern, propylene glycol fluid is used because of its low acute oral toxicity vs. the moderate acute oral toxicity of ethylene glycol. If you do not require food grade glycol (lowest oral toxicity), we recommend DOWFROST HD as it provides superior corrosion protection and low oral toxicity. If you require the lowest possible toxicity available, choose DOWFROST antifreeze (non-toxic antifreeze).
