CAS 107-21-1 Monoethylene Glycol (MEG) is one of the most important raw materials in the chemical and petrochemical industries, playing a key role in the production of polyethylene terephthalate (PET), polyester, and synthetic fibers. Due to its unique chemical properties, MEG is widely used not only in the textile industry but also in the production of PET bottles, packaging films, and even antifreeze. With the growing global demand, more than 59% of the world's MEG production is dedicated to polyester fiber manufacturing.
Key Uses of Monoethylene Glycol in PET Resin Production
About 70% of global MEG production is used to make polyester and PET resins. Without MEG, many everyday products such as sportswear, mineral water bottles, and packaging films could not be produced.
Polymerisation intermediates: Mono Ethylene Glycol MEG is a fundamental building block that combines with PTA/DMT to form long-chain polyester polymers. It is a key raw material in the synthesis of PET resin.
PET resin production: Monoethylene Glycol is used directly to manufacture polyethylene terephthalate (PET) resin, which is widely used in the production of transparent and glossy bottles for food, beverages and cosmetics.
Polyester fibre manufacturing: MEG is used as a critical, high-purity component to produce polyester fibres for textiles, imparting strength, durability and wrinkle resistance.
Performance modification (PETG): In specific applications, MEG enhances impact resistance, flexibility and thermal stability by modifying polymer structures.
Process control: It helps to ensure consistent PET quality, which is essential for efficient moulding and manufacturing processes.
As a reliable High-Purity Ethylene Glycol EG/MEG manufacturer and supplier, we provide Monoethylene Glycol (CAS 107-21-1) with strict quality control, stable large-volume supply, and comprehensive export documentation for international buyers.
