MEG CAS 107-21-1 Safety Profile & Best Practices

Monoethylene Glycol is categorized for hazard communication, and safe handling is essential. While its low volatility minimizes inhalation risks, ingestion or prolonged skin contact must be avoided. As with all industrial chemical products, consult a complete monoethylene glycol MSDS for regulatory guidance on storage, transport, and emergency measures.

Industrial & End-Use Applications of MEG CAS 107-21-1

The versatility of MEG makes it a foundational chemical across multiple sectors:

Polyester & PET Resin Manufacturing

MEG is a principal raw material in the manufacture of polyester fibers and polyethylene terephthalate (PET) resins used for textiles, bottles, films, and packaging. MEG CAS 107-21-1 accounts for the majority of its use in this segment, underlining its strategic importance to the textiles and packaging industries.

Antifreeze & Coolants

Thanks to its low freezing point and high boiling point, MEG is an indispensable component in automotive antifreeze and industrial heat-transfer fluids. These properties help engines operate safely in extreme temperatures.

Chemical Intermediates

MEG serves as a precursor to other glycols (like DEG and TEG) and a base fluid in industrial formulations, solvents, and intermediate products. It’s also employed in gas dehydration and certain specialized chemical processes.
