ETHYLENE GLYCOL Tank Chemical Compatibility of common Resins, Fittings, Gaskets and Metals
...
ETHYLENE GLYCOL
...
Ethylene glycol is a clear, colorless syrupy liquid. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since it is a liquid it can easily penetrate the soil and contaminate groundwater and nearby streams. Ethylene glycol is the most important glycol commercially available and is manufactured on a large scale in the United States. It is used as an antifreeze and coolant, in hydraulic fluids, and in the manufacture of low-freezing dynamites and resins. It has a specific gravity of 1.1.
