Best price CAS 107-21-1 Monoethylene glycol(MEG)/Ethylene glycol
It is mainly used in making polyester, polyester resin, hygroscopic agent, plasticizer, surfactant, synthetic fiber, cosmetics and explosives, as solvent for dyes/inks, antifreeze for engine, gas dehydrating agent, manufacturing resin, wetting agent for cellophane, fiber, leather and adhesive. It can produce synthetic resin PET, fiber grade PET namely polyester fiber, bottle chip grade PET for making mineral water bottle, etc. Also can produce alkyd resin, glyoxal, etc., also used as antifreeze. In addition to being used as anti-freeze agent for automobile, it is also used for conveying industrial cooling capacity, which is generally called refrigerant carrier.

Application
Here are some common applications of ethylene glycol:
1. Antifreeze/Coolant: Ethylene glycol is widely used as a primary ingredient in automotive antifreeze and coolant formulations. It helps prevent the engine from freezing in cold temperatures and also provides effective heat transfer for engine cooling.
2. Solvent: Due to its excellent solubility properties, ethylene glycol is utilized as a solvent in various industries. It is commonly used in the manufacturing of dyes, inks, paints, and resins.
3. Polyester Fiber: Ethylene glycol is a key component in the production of polyester fibers. Through a chemical reaction with terephthalic acid, it forms polyethylene terephthalate (PET), which is then spun into fibers used in textiles, carpets, and other synthetic materials.
4. Deicing Fluid: Ethylene glycol-based solutions are used as deicing fluids on aircraft, runways, and roads in cold regions. By lowering the freezing point of water, these fluids can effectively remove ice and prevent its formation.
5. Chemical Intermediates: Ethylene glycol is utilized as a chemical intermediate in the production of various compounds. It serves as a building block for the synthesis of plastics, polyurethanes, and other polymers.
6. Humectant: Ethylene glycol is employed as a humectant in personal care products and cosmetics. It helps retain moisture, prevents the product from drying out, and enhances its texture and stability.
7. Gas Dehydration: Ethylene glycol is utilized in natural gas processing to remove water and inhibit the formation of hydrates that can clog pipelines. It absorbs moisture from the gas stream, ensuring its quality and preventing corrosion.
These are just a few examples of the applications of ethylene glycol. Its versatility and properties make it a valuable compound in various industrial sectors.
