What Is Diethylene Glycol?
Diethylene glycol (DEG) is a clear, colourless, odourless, and hygroscopic liquid belonging to the glycol family. It is produced as a co-product of ethylene glycol manufacture and is widely used as a chemical intermediate, solvent, and humectant across multiple industries.
As an established diethylene glycol distributor South Africa manufacturers rely on, Nwans Chemicals supplies industrial-grade DEG suited to resin production, plasticizer manufacturing, and oilfield applications, with full documentation available on every batch.

Diethylene Glycol Applications
Polyester Resins & PET Production
DEG is used as a co-monomer in unsaturated polyester resins and certain PET formulations, improving flexibility and processing characteristics.
Plasticizers
DEG serves as a raw material in the production of plasticizers used in flexible plastics and coatings.
Industrial Solvents
Its solvency properties make DEG useful in inks, dyes, and certain cleaning formulations across manufacturing processes.
Natural Gas Dehydration
DEG is used in the oil and gas industry for natural gas dehydration and hydrate inhibition, helping remove moisture from gas streams.
Antifreeze & Heat Transfer Fluids
DEG is a component in certain antifreeze, deicing, and heat transfer fluid formulations due to its freezing-point depression properties.
