Ethylene glycol, often called MEG (Monoethylene Glycol), is one of the most widely used industrial chemicals in the world today.

It plays an important role in the production of polyester fibers, plastic bottles, and automotive coolants.

For buyers, distributors, and importers, understanding how to choose the right ethylene glycol suppliers, manufacturers, and exporters in China is essential.

This detailed guide introduces everything you need to know before purchasing: what ethylene glycol is, its main uses, technical data, advantages, packaging, typical prices, and how to find reliable Chinese factories, suppliers, distributors, and dealers.

What is Ethylene Glycol?

Ethylene glycol (chemical formula C₂H₆O₂) is a colorless, odorless, slightly viscous liquid with a sweet taste.

It is miscible with water and alcohol, but toxic if ingested. It has a molecular weight of 62.07 g/mol and is made by the hydration of ethylene oxide, which is derived from ethylene.

Ethylene glycol is the simplest diol and belongs to the group of organic compounds known as glycols. It is a vital chemical intermediate in the petrochemical industry.

Technical Data and Chemical Properties

Ethylene glycol is chemically stable, non-corrosive to most metals (when inhibitors are used), and blends well with water. These characteristics make it one of the most preferred base fluids for coolants and heat transfer systems.

What is Ethylene Glycol Used For?

1. Polyester Fiber and PET Resin Production

Over 60% of global ethylene glycol is consumed in the polyester industry. It reacts with purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) to produce polyethylene terephthalate (PET) — the base material for synthetic fibers, textiles, and plastic beverage bottles.

Many Chinese manufacturers and exporters produce ethylene glycol as part of their polyester production chain. For textile factories, buying directly from a China MEG factory can reduce costs and ensure supply stability.

2. Automotive Antifreeze and Engine Coolant

Ethylene glycol is the main ingredient in automotive antifreeze. It prevents water-based coolants from freezing in cold climates and boiling in hot conditions. Distributors and dealers who sell automotive parts often purchase bulk MEG to blend into ready-made coolant products.

3. Industrial Solvents and Resins

MEG is a versatile solvent and is used in producing alkyd resins, plasticizers, and other chemicals. Factories manufacturing paints, inks, and coatings often buy ethylene glycol from Chinese chemical suppliers in drums or ISO tanks.

4. Dehumidifiers and Heat Transfer Fluids

Ethylene glycol’s hygroscopic nature (moisture absorption ability) makes it useful for dehumidifiers and HVAC systems. It’s also used in solar heating systems and process cooling plants as a heat transfer fluid.

Advantages of Ethylene Glycol

• Wide Applications: From polyester fiber to coolant, resin, and chemical production, ethylene glycol serves multiple industries.

• Stable Chemical Performance: Resistant to degradation under normal conditions, providing long shelf life.

• Excellent Solubility: Easily mixes with water and alcohol, suitable for blending in industrial use.

• Strong Global Demand: PET packaging and textile growth keep the ethylene glycol market stable.

• Available in Bulk from China: Chinese suppliers offer cost-effective and high-quality ethylene glycol, suitable for international buyers.

Packaging Options and Storage

Storage: Keep containers tightly closed in a dry, cool, and well-ventilated place. Avoid direct sunlight and contact with strong oxidizing agents. Always handle using gloves and eye protection.

Ethylene Glycol Price

The ethylene glycol price changes with crude oil and ethylene costs, polyester industry demand, and freight rates.

For the most accurate quote, buyers should contact China suppliers, exporters, or manufacturers directly. Prices may vary based on purity, packaging type, and order size.

Most ethylene glycol factories in China offer better pricing for full-container loads (FCL). For smaller buyers, purchasing through a distributor or dealer can simplify logistics and documentation.

Major Manufacturers and Exporters in China

China has become one of the largest producers and exporters of ethylene glycol in the world. The country has modern petrochemical complexes capable of producing millions of tons per year.

Leading Chinese Manufacturers and Factories:

1. Sinopec Chemical Co., Ltd. – One of the biggest producers of ethylene and glycol products in China.

2. PetroChina Company Limited – Major integrated producer with export capacity to Asia, Africa, and Europe.

3. Wanhua Chemical Group – Offers high-purity industrial-grade and polyester-grade MEG.

4. Suneco Chemical Co., Ltd. – Known for integrated ethylene and glycol production.

5. Sanjiang Fine Chemical Co., Ltd. – Produces MEG and other ethylene oxide derivatives.

6. Tongkun Group – Supplies polyester-grade ethylene glycol for textile and PET applications.

These large-scale Chinese factories and exporters have REACH and ISO certifications, ensuring product quality and international compliance.

Distributors, Dealers, and Wholesalers

Apart from major producers, many distributors and dealers in China handle ethylene glycol for export. These companies often purchase from top factories and resell to overseas buyers in smaller quantities or customized packaging.

Why buy from distributors or dealers?

• Easier communication for small and medium orders.

• Flexible payment and shipping terms.

• Ability to consolidate mixed chemical orders.

• Local warehousing for quicker delivery.

If you are a buyer, importer, or reseller, choosing a reliable ethylene glycol distributor in China can help you avoid factory minimum order quantities and simplify export procedures.

How to Source Ethylene Glycol from China

Step 1: Identify Your Needs

Define your required grade — industrial grade (99%), polyester grade (99.8%), or high-purity grade (99.9%). Determine packaging type (drum, IBC, ISO tank) and quantity.

Step 2: Contact Verified Suppliers

Reach out to verified Chinese exporters, factories, and suppliers. Use B2B platforms or industry directories. Always ask for the supplier’s business license and export record.

Step 3: Request Technical Documents

Ask for:

• COA (Certificate of Analysis)

• MSDS (Material Safety Data Sheet)

• REACH or ISO certificates

These documents ensure you receive authentic and safe material.

Step 4: Compare Prices and Terms

Compare at least 3–5 supplier quotations. Pay attention not only to ethylene glycol price, but also to delivery time, purity, and after-sales service.

Step 5: Confirm Packaging and Logistics

Decide shipping term: FOB, CIF, or DDP. If you’re new, let the China exporter or dealer handle logistics and customs documentation.

Step 6: Order Samples

Before placing a full order, request a small sample (1–5L) to check clarity, odor, and purity. Reputable suppliers will provide free or low-cost samples.

Step 7: Negotiate Long-Term Contracts

For large-volume buyers or factories, negotiate long-term contracts with top Chinese manufacturers for better pricing and stable supply.

Tips for International Buyers

• Verify Business Licenses: Ensure the supplier is registered with the Chinese customs export system.

• Avoid Unrealistically Low Prices: Prices far below market average may indicate diluted or off-spec product.

• Check Export Experience: Reliable exporters handle all export documentation smoothly.

• Ask for Previous Export Records: Factories that already export to your country usually know local regulations.

• Consider Third-Party Inspection: Use SGS, BV, or Intertek to check product quality before shipment.

Market Outlook

The global demand for ethylene glycol continues to grow steadily. With the rise of PET packaging, textile manufacturing, and electric vehicle coolant fluids, consumption is expected to increase each year. China remains the world’s largest ethylene glycol exporter, supplying high-quality MEG to Asia, Africa, the Middle East, and South America.

For 2025, industry experts predict a stable ethylene glycol price due to balanced demand and sufficient Chinese production capacity. Buyers who lock long-term contracts with Chinese suppliers and manufacturers can benefit from more stable pricing.
