ETHYLENE GLYCOL - INDUSTRIAL GRADE{PRIVATE }
GENERIC NAMES 1,2-ethanediol; ethylene glycol; monoethylene glycol; MEG
DESCRIPTION Product is a straight-chain aliphatic compound terminated on both ends by a hydroxyl
group. It is a clear, moderately viscous, hygroscopic liquid at room temperature.
APPLICATIONS 鈥? heat transfer agents 鈥? unsaturated polyester resins
鈥? chemical intermediates 鈥? plasticizers
鈥? humectants 鈥? solvents
Large volumes of ethylene glycol are consumed as an automotive engine
antifreeze/coolant. Its hygroscopicity makes it useful as a conditioning agent in
adhesives, cork, vinyl floor tiles, synthetic rubber, cellulose sponges, printing inks and
paper products. Additionally, it is used in the production of alkyd-type resins having
linear chain structures and unsaturated polyester resins. It is also used in the
dehydration of natural gas.

PRODUCT SAFETY POLICY
It is the product safety policy of Huntsman Petrochemical Corporation to provide our customers with information
on the safe handling and use of our products. The Material Safety Data Sheet (MSDS) should always be read
and understood thoroughly before handling the product, and adequate safety procedures should be followed.
Information on the toxicity, environmental and industrial hygiene aspects of our products may be found in the
MSDS. Precautionary measures include: use only with adequate ventilation; avoid breathing vapor, mist or gas;
avoid contact with eyes, skin and clothing; keep container closed; wash thoroughly after handling.
HANDLING AND STORAGE
Ethylene glycol is a stable, noncorrosive chemical with high flash point. Since it is hygroscopic, storage vessels
must be designed to minimize moisture pickup. Other possible contaminants are iron and oxygen. For longer-
term storage, or where iron contamination and color are objectionable, resin linings or stainless steel and
aluminum vessels are recommended. Linings based on phenolic and epoxy resins are satisfactory. Zinc or zinc
alloys should not be used in glycol service. For longer-term color stability, it is recommended that the product be
stored under an inert atmosphere.
Cast-iron or centrifugal pumps with stainless shafts and impellers are satisfactory. Rubber-lined or rubber-bound
gaskets should be avoided. Flexible graphite filled or stainless steel double-jacketed gaskets are usually
effective larger gaskets. Stainless steel winding with flexible graphite filler piping gaskets performs well. Pipe
thread lubricants based on corrosion inhibiting zinc compounds or a graphite based lubricant with aluminum are
generally satisfactory; however, glycols are excellent penetrants and leaks may be present where hydrostatic
testing has indicated a tight system. Therefore, the system should be rechecked after the glycol has been added.
Low pressure stainless steel steam coils in storage tanks and steam tracing of transfer lines may need to be
provided in cases where low environmental temperatures may make pumping of the product difficult. Flushing
with water and steam can readily clean transfer or storage tanks.
SHIPPING
Product is available in tank cars, tank trucks or nonreturnable drums (510 pounds net). Containers are stainless
steel, aluminum or suitably lined. Certain government regulations may apply at the time of shipment.
