Ethylene Glycol

The production facility includes an R&D department and quality control laboratory for sample testing.

In Stock
A transparent, slightly viscous liquid without a characteristic odor. Highly soluble in water. Significantly lowers the freezing point of water, making it ideal for antifreeze, refrigeration, and heat transfer fluids.

Ethylene glycol has a wide range of applications in various industries:

  • • Used as antifreeze and coolant in automotive engine cooling systems.
  • • Ingredient in the production of antifreeze, brake fluids, and sealants.
  • • Utilized in heating systems.
  • • Chemical industry: production of plastics, varnishes, paints, synthetic resins, polymers, explosives, fragrances, etc.
  • • Pharmaceutical and cosmetic industries.

Ethylene glycol is toxic if ingested, classified as a third-class hazard. Its vapors are less toxic but pose risks with prolonged inhalation.
