Known as methyl ethyl glycol, 1,2-propanediol, or propane-1,2-diol, propylene glycol, is a synthetic, clear, colorless liquid that is widely used as an additive or antifreeze within the food, chemical ...

The specific heat capacity of ethylene glycolbased water solutions is less than that of pure water; in a 50 percent solution, ethylene glycol's specific heat capacity compared with pure water is ...

Antifreeze is one word that hydronic system owners should understand. For the hydronic HVAC contractor, this antifreeze is more accurately described as the heat transfer fluid necessary for the proper ...

Liquid cooled engines and rotating equipment use glycol-based coolants because of their superior heat transfer characteristics. However, glycol-based coolants are not necessary at all in lubrication ...

Making industrial chemicals like ethylene glycol — a key component in polymer production and familiar to many as antifreeze — consumes large amounts of energy and releases significant carbon dioxide ...
