What is ethylene glycol polyester grade?
Ethylene Glycol, Polyester Grade is a high purity grade of ethylene glycol with excellent appearance and clarity. Ethylene Glycol, Polyester Grade is used for manufacturing polyester fibers, polyethylene terephalate (PET) resins, and other materials. End products include water and drink bottles, textiles, and carpet fiber. Eastman™ Ethylene Glycol is a clear, odorless, moderately viscous, hygroscopic, and high boiling liquid. Its properties make it useful for various applications including heat transfer fluid, antifreeze, and conditioning agent.
Appearance: Clear, colorless, slightly viscous liquid.
High Purity: Typically >99.9% purity, with stringent controls on water content, iron, and Aldehydes (acetaldehyde).
Applications: Ethylene Glycol is the primary raw material for producing plastic bottles (PET), polyester textiles, carpets, and films.
Physical Properties: It has a high boiling point (197.4°C) and is hygroscopic.
Polyester grade Ethylene Glycol EG is distinct from industrial grade Ethylene Glycol used in antifreeze, as it requires a higher purity to prevent issues like color degradation or premature solidification during polymer processing.
