glycolmengsels

Glycolmengsels, a term used in some contexts, refers to liquid formulations that contain glycols—most commonly ethylene glycol or propylene glycol—dissolved in water or mixed with other solvents, often with additives. They are formulated to take advantage of glycol properties such as reduced freezing point, altered boiling point, and specific viscosity characteristics, enabling use over a wide temperature range.

Composition and variants: The base is typically a glycol–water blend. Ethylene glycol–water or propylene glycol–water mixtures are common, with glycol by volume ranging from roughly 20% to 60% depending on target freezing point and heat transfer requirements. In many industrial and automotive formulations, additives are included: corrosion inhibitors, anti-foaming agents, dyes, pH buffers, and stabilizers to prolong system life and performance.

Applications: Glycolmengsels are used as antifreezes and coolants in internal combustion engines, heat transfer fluids in solar thermal systems, and as de-icing or anti-icing fluids in aviation and road operations. They also appear in some refrigeration systems and as process fluids in chemical manufacturing.

Properties and safety: Key properties include a low freezing point relative to water, adequate heat transfer capacity, and relative chemical stability within intended use ranges. Ethylene glycol is toxic if ingested and poses environmental risks; propylene glycol is less toxic and commonly used where safety is a concern. Handling requires proper storage, spill control, and disposal in accordance with local regulations.
