Description
Antifreeze is a substance that is added to water or other liquids in order to lower their freezing point.
Antifreezes prevent liquids from freezing at low temperatures and forming ice crystals. As a result, they keep the liquid flow at negative temperatures.
Antifreeze manufacturing compounds
Alcohols:
Alcohols such as ethylene glycol and propylene glycol are the most widely used compounds for antifreeze production. They have a low freezing point and reduce the freezing point of water
This type of antifreeze for car engine and radiator
Mineral salts:
Chlorides such as calcium chloride, sodium chloride and magnesium chloride prevent water from freezing by disrupting the ice crystals.
Glycols:
Poly alkylene glycol and its derivatives are also widely used.
Methyl alcohol:
Methyl alcohol is a compound added to antifreeze to prevent corrosion of metal parts.
Alcohols such as ethanol and methanol as antifreeze in the aviation industry.
