Packaging and shipping
Tetraethylene Glycol (TEG, also known as TTEG) is a colorless, low-odor, hygroscopic and viscous liquid with the molecular formula C₈H₁₈O₄. It features low volatility, excellent thermal stability and high solubility, being fully miscible with water, ethanol, acetone and most organic solvents. With low toxicity and good chemical compatibility, TEG is a versatile industrial raw material widely used in natural gas processing, solvents, chemical intermediates and other fields.
The primary application of TEG is natural gas dehydration and gas drying. As a highly efficient desiccant, it selectively absorbs water vapor from natural gas, pipeline gas and industrial gases, reducing moisture content to meet pipeline transportation and industrial use standards. Its high boiling point and low vapor pressure make it ideal for continuous dehydration processes, ensuring stable performance and low loss during regeneration.
In the solvent industry, TEG serves as a high-boiling specialty solvent. It is used in aromatic hydrocarbon extraction to separate benzene, toluene and xylene from petroleum fractions, and as a solvent for printing inks, coatings and cleaning agents, providing slow evaporation and excellent dissolving power for resins and organic compounds. It also acts as a cosolvent in cosmetics and personal care products to improve formulation stability.
As a chemical intermediate, TEG participates in esterification and polycondensation reactions to produce plasticizers, polyester resins and polyurethane materials. It enhances the flexibility and durability of polymer products, and is also used in the production of lubricant additives, brake fluids and heat transfer fluids, offering good low-temperature performance and thermal stability.
Additionally, TEG is applied in hydraulic fluids, textile auxiliaries and gas purification processes, demonstrating its broad adaptability and value across multiple industrial sectors.
Product Description
Tetraethylene Glycol is a colorless, viscous liquid with low volatility and excellent thermal stability. It is a polyether diol featuring high purity (≥99.0%), good solubility with water, alcohols, and many organic solvents, and low toxicity.
Our TEG is packaged in 200L steel drums for industrial bulk supply and sealed HDPE containers (5L, 20L) for laboratory or small-scale needs, ensuring safe storage and transportation with its anti-leakage and corrosion-resistant packaging.
It is characterized by its high boiling point, low freezing point, and superior lubricating properties, making it adaptable to various demanding industrial environments.
In terms of usage and applications, Tetraethylene Glycol is widely used as a heat transfer fluid in high-temperature heating systems due to its excellent thermal stability. In the petrochemical industry,
it serves as a solvent and dewaxing agent for lubricating oils and fuels. It is also an important raw material in the production of polyesters, polyurethanes, and plasticizers, contributing to the manufacturing of coatings, adhesives,
and elastomers. Additionally, TEG finds application in the textile industry as a softener and in the pharmaceutical sector as an excipient. Its multifunctional properties and reliability make it a crucial component in numerous industrial and
manufacturing processes.
