Propylene Glycol Freezing Point Chart

Propylene Glycol Freezing Point Chart - Curme and johnston, reinhold publishing corp., new york (1952). Web the freezepoint temperature should be 25°f below the lowest required setpoint (see chart). It is necessary to add water or glycol to maintain proper freezepoint temperature. Propylene glycol, % by wt. °c (f°) for freeze protection volume %. A formulation of 96.0 percent food grade propylene glycol plus food grade corrosion inhibitors. Identify glycol to water ratio. Web after factoring for temperature correction, use the appropriate freeze point chart on the next page to match the specific gravity of the sample to the freezing point of the water. Web for effective freeze protection of water systems, a chart is listed below to provide the recommended inhibited propylene glycol concentrations for dowfrost™ and dowfrost™ hd glycol. Web for a mixture, the initial melting point is close to the melting point of the lightest compound in the mixture, while the initial freezing point is close to the freezing point (or melting point) of the heaviest compound in the mixture.
