MONOETHYLENE GLYCOL (MEG)
MONOETHYLENE GLYCOL (MEG) is a high-purity organic compound widely used on an industrial scale, distinguished by its low viscosity and low freezing point properties. Exhibiting superior performance particularly in polymerization processes and heat transfer applications, this chemical is manufactured in accordance with ISO 9001 and ISO 14001 quality standards.
Primary Applications
MEG is a critical intermediate and formulation component in the chemical and construction industries. Its primary applications include:
- Polyester Production: Used as a fundamental raw material in the production of polyester fibers and films.
- Automotive and Cooling: Due to its low freezing point, it serves as an excellent antifreeze agent in automotive antifreezes and industrial refrigerants.
- PET Resins: It is a fundamental building block in the production of polyethylene terephthalate (PET) used in the packaging and bottling industry.
