mono ethylene glycol uses
Polyester grade MEG is required for PET production, industrial grade is used for antifreeze, and technical grade is suitable for cost-sensitive non-critical applications.
- Polyester grade MEG (≥99.9%) is required for PET fiber, film, and bottle production due to strict purity requirements and low moisture demand (<0.05%).
- Industrial grade MEG (≥99.0%) is commonly used in automotive antifreeze systems where standard corrosion protection and thermal stability are sufficient.
- Technical grade MEG (98–99%) is suitable for non-critical industrial uses such as gas dehydration and deicing, where cost efficiency is prioritized over ultra-high purity.
