PPG 2000


view count:

PPG 2000 is a polypropylene glycol with an average molecular weight of 2000. It is a 100% active, nearly colorless, somewhat viscous liquid I.C.C polypropylene glycols are compatible with a wide range of other liquids, and at 77°F, are miscible in all proportions with most organic aromatic compounds, halogenated hydrocarbons, alcohols, aldehydes and acids. In addition, they show good solubility with some animal and vegetable oils, and modified alkyd resins. PPG 2000, as this product is also known, is a clear, viscous liquid at room temperature. It has a higher pour point and, unlike the lower molecular weight PPGs, is partially soluble in water at 25 °C. It loses its water solubility at higher temperatures. Like all polypropylene glycols, Polyglycol 2000 is soluble in all proportions with any organic solids and liquids, the main exception being long chain aliphatic hydrocarbons. Polyglycol 2000 possesses excellent lubricity and has a low vapour pressure. Under extreme heating conditions it does not form coke not does it form a varnish. Decomposition products are low boiling products that are either lost as volatiles or soluble in the polypropylene glycol.

Safe Use and Handling


I.C.C polypropylene glycols are relatively easy to store and handle. They can be stored in bulk in steel tanks, which should be padded with nitrogen or any other inert gas to prevent air from entering the tank. If slight iron pickup and colour changes cannot be tolerated then the storage tanks should be constructed from stainless steel.

To ease the handling of polypropylene glycols somewhat, higher storage temperatures should be considered to keep the viscosity of the polyglycols within limits suitable for the pumping equipment available. The maximum storage temperature should not exceed 40°C to avoid the risk of product degradation. Pipelines may also require insulation and/or tracing to maintain suitable product temperatures.

Although PPGs have very low pour points, especially polyglycols 2000 and 4000 become very viscous at low temperatures. Consequently it is recommended that they be stored in tanks which are well insulated and heated. Externally located heating devices are preferable to internally sited ones. With external heating the risk of accelerating product deterioration is greatly reduced.

Similarly drums should be stored under cover or preferably inside a warehouse, to maintain the temperature of the polyglycol at a level which allows for easy discharge.

The shelf life of properly stored bulk and unopened drums is, at least, 24 months.


Toxicological Information

Polyglycols 2000 and 4000 are considered to be low in acute oral toxicity, whereas polyglycols 400, 600, 1000 and 1200 are considered to be low to moderate in acute oral toxicity.

They cause no significant skin irritation or sensitization and are not reportedly absorbed in any appreciable amount. Direct contact with the eyes may cause slight temporary irritation, similar in character to that caused by mild soap. Consequently it is recommended that eye protection should be employed and viewed as the minimum level of safety equipment required when working with polypropylene glycols.
