Product Overview

Ethylene glycol, commonly referred to as monoethylene glycol or MEG, is a colorless to slightly yellow viscous liquid with a sweet odor and broad industrial utility. As the simplest vicinal diol, it serves as the primary monomer in polyethylene terephthalate (PET) production, a key component in antifreeze and coolant formulations, and a versatile solvent and humectant across multiple industries. Dideu supplies industrial grade ethylene glycol at 99.9% minimum assay in tonnage quantities to customers in global markets.

Key Attributes

Key Highlights

• HIGH PURITY: Standard industrial grade at 99.9% minimum assay, meeting the stringent requirements of polyester fiber and bottle-grade PET production.
• LOW COLOR AND IMPURITIES: Color controlled to 5 APHA maximum, with diethylene glycol not more than 0.05%, chloride not more than 1 ppm and iron not more than 0.1 ppm, ensuring consistent polymerization performance.
• LOW WATER CONTENT: Water content is controlled to 0.08% maximum, which minimizes side reactions during esterification and transesterification processes.
• TONNAGE CAPACITY: Supplied from large-scale MEG production facilities, supporting ISO tank and flexitank shipments for continuous plant feed.
• FLEXIBLE PACKAGING: Available in ISO tanks, flexitanks, IBC totes and drums, accommodating both bulk contract supply and smaller spot orders.
• VERSATILE APPLICATIONS: Serves as a monomer for PET, a freeze-point depressant in antifreeze, a polyol for unsaturated polyester resins, and a hygroscopic agent in gas dehydration.
• FULL DOCUMENTATION: Every shipment is accompanied by a Certificate of Analysis covering assay, water, color, DEG content and trace impurities.
• RELIABLE LEAD TIME: Orders are arranged within 3 weeks and shipped by sea to ports worldwide.

Product Description

Ethylene glycol is the most commercially significant vicinal diol and one of the highest-volume organic chemicals produced globally. The product is offered as a colorless to slightly yellow viscous liquid at 99.9% minimum assay, suitable for polyester-grade and fiber-grade applications where low color and tight impurity control are essential. Each batch is manufactured to consistent specifications so that it performs predictably in high-temperature esterification and polycondensation processes.

The value of ethylene glycol lies in its two hydroxyl groups, which enable it to function as a bifunctional monomer in step-growth polymerization with dicarboxylic acids and their esters. Its complete miscibility with water makes it an effective freeze-point depressant and heat-transfer fluid component, while its hygroscopic nature supports use as a desiccant in natural gas processing. The compound also serves as a solvent for dyes, inks and coatings, and as a humectant in cosmetic and personal care formulations where moisture retention is required.

Dideu Group supplies ethylene glycol with a minimum order quantity of 1 metric ton. Orders are prepared within 3 weeks and shipped by sea. Standard documentation includes a Certificate of Analysis and technical data for incoming quality control.

Applications

PET Polyester and Fibers. Ethylene glycol is the primary diol monomer in the manufacture of polyethylene terephthalate (PET), used for beverage bottles, textile fibers, packaging films and engineering plastics. Its purity and low impurity profile directly influence polymer molecular weight and end-product clarity.

Antifreeze and Coolants. As a freeze-point depressant, ethylene glycol is the principal component in automotive engine coolants and industrial heat-transfer fluids, providing reliable low-temperature protection and corrosion inhibition when formulated with appropriate additives.

Unsaturated Polyester Resins. The compound serves as a polyol building block in the synthesis of unsaturated polyester resins used for fiberglass-reinforced composites, gel coats, marine laminates and construction materials.

Gas Dehydration and Natural Gas Drying. Ethylene glycol functions as a hygroscopic desiccant in glycol dehydration units, removing water vapor from natural gas streams to prevent hydrate formation and pipeline corrosion.

Cosmetics and Personal Care. Used as a humectant and solvent in skin care, hair care and oral hygiene products, ethylene glycol helps retain moisture and improve formulation stability.

Deicing Fluids. Ethylene glycol-based formulations are employed as aircraft and runway deicing fluids, where low freezing point and controlled viscosity ensure effective ice removal under cold-weather conditions.

Solvents and Chemical Intermediates. The compound acts as a solvent for dyes, inks, adhesives and coatings, and as a starting material for the synthesis of glycol ethers, esters and other derivative chemicals.

Specifications

Packaging and Shipping

Storage Recommendations

• Keep containers tightly closed when not in use.
• Store in a cool, dry and well-ventilated warehouse.
• Protect from direct sunlight and prolonged exposure to heat.
• Keep bulk containers sealed between transfers, as the product is hygroscopic and absorbs moisture from humid air.

Shipping method: By sea, in ISO tanks, flexitanks or container loads.

Lead time: Within 3 weeks after order confirmation.
