Glycols
Glycols are essential intermediates in the manufacturing of polyester fibers, packaging, and resins. They are also utilized in everything from glues and film to antifreeze and plasticizers. MEG, DEG and TEG – three ethylene glycols are virtually odorless, colorless, stable liquids with low viscosities and high boiling points that have many similar chemical characteristics. MEG is used as antifreeze in engine coolant, fibres treatment, paper, adhesives, printing inks, leather and cellophane films. DEG serves as a dehydration agent. It is also used in the treatment of corks, glue, paper and cellophane films. TEG is used as liquid desiccant for the dehydration of natural gas and as a dehumidifier in air conditioning systems. TEG also finds use as a vinyl plasticiser and as a solvent in many miscellaneous applications.
