Glycolblandning

Glycolblandning refers to a mixture where ethylene glycol or propylene glycol is the primary component, typically diluted with water. These mixtures are commonly used for their freeze-point depression and boiling-point elevation properties. The specific ratio of glycol to water dictates the performance characteristics of the blend.

Ethylene glycol and propylene glycol are organic compounds with two hydroxyl groups. Ethylene glycol is a highly effective antifreeze but is toxic if ingested. Propylene glycol is less toxic and is often preferred for applications where accidental contact or ingestion is a concern, such as in food processing or HVAC systems.

The primary application of glycolblandning is in automotive antifreeze/coolant, where it prevents the engine from overheating in summer and freezing in winter. It also contains additives to prevent corrosion and cavitation within the cooling system. Beyond automotive uses, glycolblandning can be found in hydronic heating and cooling systems, solar thermal systems, and as a de-icing fluid for aircraft. The exact composition and additives in a glycolblandning are often proprietary and tailored to specific applications and performance requirements.
