Widely used as an antifreeze agent in automotive cooling systems, preventing freezing in winter and overheating in summer due to its low freezing and high boiling points. It is a key raw material in the production of polyester fibers and polyethylene terephthalate (PET) used for plastic bottles and packaging. Employed in the manufacture of resins, paints, and solvents. Also utilized in deicing fluids for aircraft and in some hydraulic and brake fluid formulations. Its ability to lower the freezing point of water makes it essential in chilled water systems for air conditioning and industrial processes.
