Triethylene glycol (TEG)

Is a by-product of ethylene glycol (MEG) and diethylene glycol (DEG) production. Grade A is used as feedstock in production of oligoester acrylates, polyesteracrylates, plasticizers and other products of organic synthesis. Grade B is used for dehumidification of gas and air in the production of antifreezes and oligoester acrylates.
