Products Description of Industrial Ethylene Glycol CAS#107-21-1
Polyester-grade ethylene glycol is refined from petrochemical ethylene raw material via multi-stage distillation and deep purification process, precise strict control on diethylene glycol, total aldehyde and moisture impurities can effectively prevent polyester chips from yellowing, poor transparency and insufficient tensile strength during high-temperature polycondensation reaction. The stable content index fully matches large-scale continuous PET polymerization production technical standard required by domestic and overseas polyester manufacturers, avoiding frequent parameter adjustment in production line caused by unstable raw material quality.

Product Application of Industrial Ethylene Glycol CAS#107-21-1
Mainly applied as core polymerization raw material for food-grade PET bottle chip, textile polyester staple fiber, filament yarn and unsaturated alkyd resin manufacture. Besides mainstream polyester industry, it is also used as solvent and reaction medium for certain fine chemical synthesis projects. Bulk shipment by ISO tank container or full bulk tanker is available, long-term annual supply framework contract and customized preferential quotation can be offered for large polyester manufacturers, full set of export certification documents and inspection certificates are attached for overseas import inspection and customs clearance.
