INHIBITED PROPYLENE GLYCOL
1,2-PROPANEDIOL
Inhibited propylene glycol is a non toxic liquid that is practically colourless, odourless, and tasteless. It is used in chillers, glycol systems, boiler systems, vehicles, solar panels, and many other water systems that require freeze protection or improved heat transfer. The corrosion inhibitor is an organic inhibitor designed to protect all common metals in water systems. The inhibitor system is designed to protect metals commonly found in mechanical systems such as brass, copper, solder, steel, and cast iron. Just dilute with water to your required freeze protection temperature as in the chart below.

USES FOR PROPYLENE GLYCOL:
- For use in solar boilers / heaters as a heat transfer fluid. To use dilute the propylene glycol 1:1 with water.
- Non-toxic antifreeze;
- Substitute for ethylene glycol and glycerol
- As a coolant in liquid cooling systems.
DEPRESSION OF FREEZING POINT OF WATER:
Propylene glycol is a component in newer automotive antifreezes and de-icers used at airports. Like ethylene glycol (MEG), the freezing point of propylene glycol is depressed when mixed with water due to disruption of hydrogen bonding. Unlike ethylene glycol, propylene glycol is much lower in toxicity. It is readily biodegradable.
Freezing Points of Propylene Glycol / Water Mixtures Percent
(For example: a 30% propylene glycol : 70% water mix will depress the freezing point down to –30C)
