MEG Supplier & Exporter — Fibre-Grade Monoethylene Glycol
C₂H₆O₂ Monoethylene Glycol · Fibre Grade 99.8%
Fibre-grade monoethylene glycol at 99.8% minimum purity with diethylene glycol and water each below 0.08%, iron below 0.1 mg/kg and UV transmittance certified at 220, 275 and 350 nm — the optical set a polyester or PET line is qualified on. Supplied under nitrogen blanket in ISO tanks or new drums with a batch-specific Certificate of Analysis.

MEG — Full Technical Analysis
Fibre-grade specification: chemistry first, then the UV transmittance and boiling range that separate a polyester-grade glycol from an industrial one.
| Property | Unit | Test Method | Specification |
|---|---|---|---|
| Appearance | — | ASTM D-4176, visual | Colourless, transparent |
| Purity | wt% | SMS-2886 | 99.8 min |

| Specific Gravity 20/20 °C | — | ASTM D-4052 | 1.1151 – 1.1156 |
| UV Transmittance at 220 nm | % | SMS-1997 | 80 min |
| UV Transmittance at 275 nm | % | SMS-1997 | 95 min |
| UV Transmittance at 350 nm | % | SMS-1997 | 99 min |
| Boiling Range, 5% vol | °C | ASTM D-1078 | 196 min |
| Boiling Range, 95% vol | °C | ASTM D-1078 | 199 max |
Boiling range is measured at 0.1013 MPa. Ash can be tightened to 10 mg/kg on request. Some producer standards specify 70% minimum UV transmittance at 220 nm — confirm the figure your line needs at enquiry stage and we will match the certificate to it.

Applications
Roughly nine tenths of world MEG goes into polyester in one form or another; the rest is antifreeze, resins and gas processing.
Polyester Fibre & Yarn
Reacted with PTA to make PET fibre, filament and staple.
PET Resin & Packaging
Bottle-grade resin for beverages and food packaging.
Antifreeze & Coolants
Engine and industrial coolant with corrosion inhibitors.
Unsaturated Polyester Resins
UPR and alkyd resin production for coatings and composites.
Natural Gas Dehydration
Hydrate inhibition and water removal in gas processing.
Heat Transfer Fluids
Secondary coolant loops in HVAC and process chilling.
Humectants & Plasticizers
Cellophane, adhesives, inks, leather and paper.
De-icing Fluids
Aircraft and runway de-icing formulations.
Solvent & Intermediate
Feedstock for glycol ethers, esters and 1,4-dioxane-free specialities.
Packaging, Logistics & Trading Terms
How we load, blanket, certify and ship bulk MEG. Terms can be adapted by agreement — tell us what your operation needs.
- Minimum Order Quantity
- 1 × 20 ft ISO tank (approx. 20 MT). Larger parcels by bulk vessel. Drummed trial quantities available for qualification.
- Packaging
- ISO tank container, 220 L (220 kg net) new drums four to a strapped pallet, or bulk parcel. Drums and tanks are supplied under a nitrogen blanket.
- Incoterms & Loading Ports
- EXW, FOB, CFR and CIF (Incoterms® 2020). Standard loading at Bandar Abbas and Bandar Imam Khomeini; other ports by arrangement.
- Quality Certification
- Batch-specific CoA with every shipment covering purity, DEG, water, colour, iron, chlorides, ash and UV transmittance at all three wavelengths. SGS / Bureau Veritas inspection at buyer’s cost.
- Lead Time
- 7–14 days for standard grades after order confirmation; 15–25 days when new drums or dedicated tank capacity have to be scheduled.
- Storage & Handling
- Store under a nitrogen blanket at ambient temperature in closed containers away from oxidising agents. MEG is strongly hygroscopic — an open drum picks up water and fails the 0.08% limit long before anything else on the certificate moves. Harmful if swallowed; a Safety Data Sheet ships with every consignment.
Certificate of Analysis
A batch-specific CoA is issued with every shipment. Third-party inspection by SGS, Bureau Veritas or an inspector of your choice can be arranged at the buyer’s cost.
