How are the ash content and flash point of ethylene glycol classified?
2026-02-28
Ethylene Glycol Ash content (inorganic residue after evaporation and ignition):
Ethylene Glycol High Grade: ≤ 0.001%
Medium Grade: 0.001%–0.005%
Low Grade: > 0.005% (may contain significant impurities)
Chemical stability is evaluated via heating tests: high-grade Ethylene Glycol EG shows minimal color change and no sediment after heating, while significant discoloration and sediment indicate low grade.
Ethylene Glycol Flash point is critical for safety:
Ethylene Glycol High Grade: ≥ 110°C
Medium Grade: 105–110°C
Low Grade: < 105°C (higher fire risk during storage and use)
