Jäätumisvastaseid

Jäätumisvastaseid is a Finnish term that translates to "antifreeze" in English. It refers to a substance added to water to lower its freezing point. Antifreeze is commonly used in automotive cooling systems to prevent the water in the radiator from freezing during cold weather, which could cause significant damage to the engine. It also serves the opposite function in warmer temperatures by raising the boiling point of the coolant, preventing the engine from overheating.

The most common type of antifreeze is based on ethylene glycol or propylene glycol. These chemicals are mixed with water, typically in a 50/50 ratio, to achieve optimal freezing and boiling point protection. The specific concentration can be adjusted depending on the expected climate conditions. Antifreeze also contains additives that protect the cooling system components from corrosion and scale formation.

Beyond automotive applications, antifreeze solutions are used in various other systems where freezing is a concern. This includes heating systems in buildings, industrial cooling processes, and even in aircraft de-icing fluids, although the formulations for de-icing are often different and designed to evaporate quickly. Proper handling and disposal of antifreeze are important due to the toxicity of its primary components, particularly ethylene glycol.
