Polyglycol P 4000 E
Linear polymer produced by controlled, catalysed reaction between propylene oxide and water. The letter P and the number 4000 indicate that the polymer is propylene oxide based and that the approximate average molecular weight is 4000.
PPG P-4000E, 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 P-4000E is soluble in all proportions with any organic solids and liquids, the main exception being long chain aliphatic hydrocarbons.
Polyglycol P-4000E possesses excellent lubricity and has a low vapour pressure. Under extreme heating conditions it does not form coke nor does it form a varnish. Decomposition products are low boiling products that are either lost as volatiles or soluble in the polypropylene glycol.
