Triethylene Glycol (TEG)

Brief Introduction:
Triethylene glycol (TEG) is a chemical compound with the formula C₆H₁₄O₄, recognized as a colorless, viscous liquid. This substance is primarily used in the petrochemical industry and as an intermediate in the production of various chemicals. Due to its moisture-absorbing properties and low freezing point, triethylene glycol is particularly utilized in cooling systems and antifreeze formulations.

Product Category:
Triethylene glycol falls under polyols and industrial chemicals.

Applications:

1. Antifreeze and Coolants:
   Functions as an effective agent in the production of antifreezes and coolants to prevent freezing in heating and cooling systems.
2. Moisture Absorber:
   Used in various industries as a moisture absorber to control humidity in products such as paints and coatings.
3. Chemical Production:
   Serves as a raw material in the production of other chemical compounds, including fatty acids and esters.
4. Textile Industry:
   Acts as a softening and moisturizing agent in the production of textiles and fibers.
