Description
Ethylene Glycol is a vital, high-volume industrial chemical primarily recognized for its exceptional antifreeze and coolant properties. Its high boiling point, low freezing point, and hygroscopic nature make it indispensable across numerous manufacturing sectors. This versatile compound is a critical raw material for global industries, including automotive, textiles, packaging, and chemical synthesis.
Application
- Antifreeze & Coolants: The primary application, used in automotive and industrial cooling systems to prevent freezing and overheating.
- Polyester Production: A key monomer in the manufacture of polyethylene terephthalate (PET) resin for fibers, films, and plastic bottles.
- Dehydrating Agent: Used in natural gas processing to remove water vapor and prevent hydrate formation in pipelines.
- Chemical Intermediate: Serves as a building block for synthesizing various chemicals, including glyoxal, ethers, and polyester polyols for urethanes.
- Hydraulic & Brake Fluids: A component in formulations requiring stable viscosity and low-temperature performance.
- Solvents & Coatings: Used in paints, inks, and dyes as a solvent and humectant to control evaporation and viscosity.
- Heat Transfer Fluids: Employed in closed-loop heating, ventilation, and air conditioning (HVAC) systems and solar thermal collectors.

Quality Control
Our Ethylene Glycol is manufactured under stringent quality management systems to ensure batch-to-batch consistency and reliability. We supply various grades, including high-purity industrial and fiber-grade, meeting relevant industry specifications. A comprehensive Certificate of Analysis (COA) detailing purity, water content, acidity, and other critical parameters is provided with every shipment to guarantee compliance with your technical requirements.
Storage
Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. Keep container tightly sealed to minimize absorption of atmospheric moisture (hygroscopic). Recommended storage temperature is between 15°C and 25°C.
