99% Monoethylene Glycol Applications / Uses
1. Ethylene Glycol mainly used for making polyester fiber, polyester resin, dehumidifying agents, plasticizers, surfactant, synthetic fibers,
2. MEG can be used as a dye / ink solvent, the preparation of the engine antifreeze, gas dehydration.
3. For the production of synthetic resin, PET, or polyester fiber grade PET, bottle grade PET film used to produce mineral water bottles.
4. Ethylene Glycol can also produce alkyd resins, also used as antifreeze.
