Product Application of Ethylene glycol CAS#107-21-1
Ethylene glycol is widely used as antifreeze for various heating and cooling systems, such as car radiators and aircraft engine cooling systems. It also serves as a key component in hydraulic brake fluids. In industry, it acts as a solvent for coatings, plastics and inks, a softener for cellophane materials, and an important raw material for producing plasticizers, elastomers, alkyd resins, synthetic fibers and wax products.
