乙二醇 High Purity Mono Ethylene Glycol (MEG) 聚酯级高纯防冻液与聚酯树脂合成原料

Mono Ethylene Glycol (MEG, CAS 107-21-1) is a premium, high-purity, colorless, transparent, and slightly viscous liquid free from mechanical impurities. It is practically odorless with a faint sweet taste and exhibits strong hygroscopic affinity. MEG is completely miscible in all proportions with water, ethanol, acetone, glycerin, and mainstream polar aliphatic solvents. As the simplest aliphatic diol, MEG serves as an indispensable foundational petrochemical building block globally. Its primary consumption lies in polymer chemistry as a key co-monomer for synthesizing polyester fibers (terylene), PET bottle flakes, engineering plastics, and unsaturated polyester resins (UPR). Concurrently, due to its outstanding ability to drastically depress the freezing point of aqueous solutions, it operates as the premier active fluid component in automotive antifreezes, industrial coolants, and de-icing formulations.

Technical Specifications & Physical Properties

Core Applications

• Polyester Fibers & PET Packaging: Functions as the mandatory co-reactant in manufacturing Polyethylene Terephthalate (PET) chains, heavily specified in manufacturing synthetic terylene textiles, food-grade beverage bottles, and specialized packaging films.

• Heavy-Duty Antifreezes & Coolant Fluids: Deployed as the primary antifreeze agent in automotive engine cooling jackets, HVAC heat-transfer media, and massive industrial refrigeration loops to offer elite freeze-and-boil protection.

• Synthetic Resins & Polyurethanes: Extensively chemically targeted to synthesize alkyd enamels, unsaturated polyester resins (UPR), and polyurethane (PU) formulations to balance backbone flexibility and chemical toughness.

• Process Solvents & Gas Processing: Utilized as a high-boiling carrier solvent and wetting agent in processing electronic chemicals, dynamic printing inks, leather tanning dyestuffs, and industrial gas dehydration systems.

Packaging & Storage

• Packing: Packaged in standard 230 KGS net weight iron or HDPE plastic drums. Industrial wholesale trade fully utilizes 1000 KGS IBC containers or international bulk ISO TANK networks for reliable maritime shipping.

• Storage: Store inside a completely cool, dry, and well-aerated dedicated chemical facility (protect meticulously from moisture due to its strong hygroscopic kinetics). Keep far away from open flames, sparks, and direct sunlight. Keep all closures hermetically sealed and isolate from powerful oxidizers and acids.
