Monoethylene Glycol (MEG): Premium Petrochemical Solution for Industrial Needs

Introduction

Monoethylene glycol (MEG), also known as ethylene glycol, is a versatile organic compound widely recognized as a cornerstone in the petrochemical industry. As a clear, colorless, and slightly viscous liquid, petrochemical MEG serves as a critical raw material in the production of polyester fibers, resins, and antifreeze formulations. Its industrial importance stems from its excellent hygroscopic properties and low volatility, making it indispensable for manufacturing processes that demand high performance and reliability. For international B2B buyers seeking a dependable monoethylene glycol supplier, MEG export from Iran offers high-quality options backed by robust production capabilities. In a global market driven by sustainability and efficiency, petrochemical MEG continues to play a pivotal role in advancing sectors like textiles, packaging, and automotive, ensuring products meet modern demands for durability and environmental compatibility.

Technical Specifications

Understanding the technical specifications of industrial ethylene glycol is essential for buyers evaluating its suitability for specific applications. Petrochemical MEG typically features a molecular formula of C2H6O2 and a CAS number of 107-21-1. It appears as a clear, colorless liquid with no discernible odor, boasting a purity level of at least 99.8% in premium grades.

Key physical properties include a boiling point range of 196–199°C at atmospheric pressure, a freezing point of -13°C, and a density of approximately 1.115 g/cm³ at 20°C. Chemically, MEG antifreeze exhibits excellent miscibility with water, alcohols, and aldehydes, with a viscosity of about 16.1 mPa·s at 25°C. Performance attributes encompass a flash point of 111°C (closed cup) and a refractive index of 1.430–1.432 at 20°C. Acidity, measured as acetic acid, is kept below 0.005%, while water content is minimized to 0.08% maximum to prevent degradation.

For monoethylene glycol suppliers focused on MEG export from Iran, these specifications ensure consistent quality, with low levels of impurities like diethylene glycol (DEG) at under 0.1%. Such detailed properties make industrial ethylene glycol ideal for processes requiring precise thermal stability and solvent capabilities, as substantiated by industry standards.

Applications

The applications of MEG span numerous industries, highlighting its role as a multifaceted petrochemical MEG. In the textile sector, MEG for polyester is fundamental, serving as a precursor in producing polyethylene terephthalate (PET) fibers and resins, which account for over 70% of global MEG consumption. This enables the creation of durable fabrics, apparel, and technical textiles with superior strength and wrinkle resistance.

In the automotive and HVAC industries, MEG antifreeze is widely used in coolants and heat transfer fluids, protecting engines from freezing and overheating while enhancing system efficiency in gas compressors and ventilation setups. Packaging benefits from industrial ethylene glycol in PET bottle production, offering lightweight, recyclable solutions for beverages and consumer goods.

Additionally, MEG plays a vital role in natural gas processing as a hydrate inhibitor, preventing pipeline blockages in cold environments. Other uses include de-icing fluids for aviation, inks, coatings, and even pharmaceutical intermediates. For buyers sourcing from a monoethylene glycol supplier, these diverse applications underscore MEG’s value in driving innovation across plastics, detergents, and energy sectors.

Export & Supply Insights

Global demand for petrochemical MEG is surging, particularly in regions like Asia, the Middle East, Africa, and Europe, where rapid industrialization fuels the need for MEG export from Iran. Asia-Pacific leads with over 57% market share, driven by textile and packaging booms in China and India, making it a prime destination for industrial ethylene glycol shipments.

Middle Eastern buyers value MEG for polyester in oil and gas applications, while African markets seek MEG antifreeze for infrastructure development. European importers prioritize sustainable sources, appreciating Iran’s competitive pricing and proximity for efficient logistics. As a key monoethylene glycol supplier, Iran exports high volumes via bulk, drums, or IBCs, benefiting from strategic ports and production capacities exceeding millions of tons annually. This positions MEG export from Iran as a reliable option amid fluctuating global supplies, with forecasts predicting market growth to USD 57 billion by 2033.
