Product properties*)
Polyglykol B11/30 is a clear neutral viscous liquid at room temperature. Polyglykol B11/30 can be supplied in tank trucks, steel drums or 1-t-containers. Its ether groups as well as the ethyleneoxid/propyleneoxid ratio and the hydroxy end group mainly control the physical and chemical properties of Polyglykol B11/30. Therefore Polyglykol B11/30 is soluble in water and polar organic solvents like aceton or methanol at room temperature. Polyglykol B11/30 is insoluble in pure hydrocarbons.. The cloud point of Polyglykol B11/30 is 58°C. Polyglykol B11/30 displays a very low solidification point of –50°C and no evaporation loss even at temperatures as high as 100°C.
