WebEthylene glycol based antifreeze has a low freezing point, which depends on the concentration of the substance. In this case, the liquid inside the cooling system begins to crystallize in the range from 0 to -70 ° C. When choosing a quality antifreeze, it is necessary to take into account the operating conditions of the machine. WebThe common name ethylene glycol literally means “the glycol derived from ethylene .”. Ethylene glycol is a clear, sweet, slightly viscous liquid that boils at 198 °C (388.4 °F). Its most common use is as an automotive antifreeze. A 1:1 solution of ethylene glycol and water boils at 129 °C (264.2 °F) and freezes at −37 °C (−34.6 °F ...
