Types of Ethylene Glycol
Monoethylene Glycol (MEG)
Monoethylene glycol is the most commonly used form of ethylene glycol. It has a minimum purity of 99.8% and is primarily utilized in the production of polyethylene terephthalate (PET) for bottles and textiles. MEG is also a key component in antifreeze formulations, providing excellent thermal stability and low freezing points.
Diethylene Glycol (DEG)
Diethylene glycol is a less common variant that has a minimum purity of 99%. DEG is primarily used as a solvent and plasticizer, enhancing the flexibility and durability of various materials. It is also utilized in antifreeze formulations, although to a lesser extent than MEG.
Triethylene Glycol (TEG)
Triethylene glycol is another derivative of ethylene glycol, characterized by a minimum purity level of 98%. TEG is often employed as a dehydrating agent in natural gas processing and as a solvent in various industrial applications. Its high boiling point makes it suitable for use in high-temperature environments.
