Product Application
Diethylene glycol (DEG) is a widely used solvent and raw material in many industrial and consumer goods. It serves as a dehydrant for natural gas treatment; a lubricant and finishing agent in textile processing; a component in brake fluids, lubricants, antifreeze, wallpaper removers and artificial smoke fluids; a solvent for printing inks and textile dyes; and an intermediate for manufacturing resins, triethylene glycol, surfactants, as well as diethylene glycol esters and ethers.
