Applications Of Monoethylene Glycol MEG
Polyester and PET Resin Manufacturing
Mono Ethylene Glycol (MEG) serves as the primary raw material for producing polyester fibers and polyethylene terephthalate (PET) resins, materials widely used in textiles, bottles, films, and packaging. MEG with CAS number 107-21-1 accounts for the vast majority of consumption in this sector, underscoring its strategic importance to the textile and packaging industries.
Antifreeze and Coolants
Leveraging its low freezing point and high boiling point, Monoethylene Glycol MEG serves as an indispensable component in automotive antifreeze and industrial heat transfer fluids.
Chemical Intermediates
MEG functions as a precursor for other diols (such as diethylene glycol DEG and triethylene glycol TEG) while also acting as a fundamental fluid in industrial formulations, solvents, and intermediate products.
As a reliable High-Purity Ethylene Glycol EG/MEG manufacturer and supplier, we provide Monoethylene Glycol (CAS 107-21-1) with strict quality control, stable large-volume supply, and comprehensive export documentation for international buyers.
