Standard post
Triethylene glycol (TEG) and tetraethylene glycol (TETRA EG) may be used directly as a plasticizer, TEG and TETRA EG are used in the manufacture of:
- Safety glass
- Separation membranes (silicone rubber, polyvinyl acetate, cellulose triacetate)
- Ceramic materials (resistant refractory plastics, molded ceramics)
Demand for tetraethylene glycol is strong in the area of BTX (benzene, toluene, xylene) extraction to separate aromatic hydrocarbons from non-aromatic hydrocarbons.
Monoethylene glycol (MEG), diethylene glycol (DEG) are often used in water-based paints, dry-wall compounds, glass cleaners, dyes, waxes and adhesives as a freezing point depressor to avoid damage by low-temperature extremes.
In addition, mono-ethylene glycol and diethylene glycol are also used as binders for foundry sand molding, and a lubricant for glass- and cement-grinding. In addition, both homologs are also used as humectants in textile fiber, paper, leather, adhesive and glue applications.
