Ethylene Glycol (MEG) Supplier — 99% Industrial & 99.9% Fiber Grade from China
Mono Ethylene Glycol (MEG, CAS 107-21-1) is the world's most widely produced glycol, with global demand exceeding 30 million tons annually. From PET bottles to polyester textiles, from antifreeze to natural gas dehydration — MEG is the backbone of countless industries. At VASTEC, we supply two purity grades of MEG to buyers in 30+ countries, with flexible packaging and competitive factory-direct pricing.
What Is Ethylene Glycol?
Ethylene Glycol (C₂H₆O₂, molecular weight 62.07) is a colorless, viscous, nearly odorless liquid with a sweet taste (toxic — never taste chemicals!). It is miscible with water and many organic solvents. With a boiling point of 197°C and freezing point of -12.9°C, MEG is a versatile chemical intermediate and functional fluid.
Two Purity Grades for Different Industries
Not all MEG is created equal. The purity grade determines which applications the product is suitable for. VASTEC supplies both grades from trusted Chinese manufacturers with consistent quality.
1. Industrial Grade MEG — 99% Purity
Our industrial grade MEG (≥99% purity) is designed for applications where high purity is important but fiber-grade specifications are not required. This is the cost-effective choice for bulk industrial use.
- Antifreeze & engine coolant — The primary use of industrial MEG worldwide, providing freeze protection down to -37°C
- HVAC & heat transfer systems — Chiller fluids, solar thermal systems, geothermal heat pumps
- Natural gas dehydration — Removing water from natural gas pipelines to prevent hydrate formation
- Chemical intermediate — Raw material for ethylene glycol ethers, glycolaldehyde, and oxalic acid
- Concrete additives — Frost protection during cold-weather concrete pours
- Textile processing — Sizing agent and dye carrier in textile manufacturing
Typical specs: Purity ≥99%, Water ≤0.2%, Diethylene Glycol (DEG) ≤0.5%, Color (APHA) ≤10, Acidity ≤0.02%
2. Fiber/PET Grade MEG — 99.9% Purity
Our high-purity MEG (≥99.9%) meets the stringent specifications required for polyester fiber spinning and PET resin production. Low DEG content and minimal impurities ensure consistent polymerization and high-quality end products.
- PET resin production — The largest application: MEG reacts with PTA to produce PET chips for bottles, films, and sheets
- Polyester fiber (PFY/PSF) — Staple fiber, filament yarn, and nonwoven fabric production
- Engineering plastics — PBT (polybutylene terephthalate) production for automotive and electronics
- Specialty chemicals — High-purity MEG for pharmaceutical and cosmetic formulations
Typical specs: Purity ≥99.9%, Water ≤0.1%, DEG ≤0.1%, Color (APHA) ≤5, Acidity ≤0.005%, Iron ≤0.1 ppm
