Ethylene glycol

MEG - DEG - TEG

Ethylene Glycols

Ethylene glycol is a chemical commonly used in many commercial and industrial applications including antifreeze and coolant.  Ethylene glycol helps keep your car’s engine from freezing in the winter and acts as a coolant to reduce overheating in the summer. Other important uses of ethylene glycol include heat transfer fluids used as industrial coolants for gas compressors, heating, ventilating, and air-conditioning systems, and ice skating rinks.Ethylene glycol also is used as a raw material in the production of a wide range of products including polyester fibers for clothes, upholstery, carpet and pillows; fiberglass used in products such as jet skis, bathtubs, and bowling balls; and polyethylene terephthalate resin used in packaging film and bottles.  Many of these products are energy saving and cost efficient as well as recyclable.  

 Glycol family products are versatile compounds used in the fields include;

- Anti-freezing and anti-icing additive
- Intermediate in polymer production and chemical reaction
- Solvent or plasticizer for plastic, lacquer, paint and varnish
- Hydraulic, brake, thermal exchange fluids and fuel additive

- Dehydrating
- Coupling printing inks
- Textile conditioning
- Solvent for dyes in textile and leather finishing
- Agricultural formulation
- General purpose cleaners
- Explosives manufacture
- Electrolytic componen
- Humectan
- Water-based coating
- Preservative, rust remover, and disinfectan
