Product Properties
  • POLYGLYKOL D 21/700 is a clear, neutral viscous liquid at room temperature. POLYGLYKOL D 21/700 is soluble in water and polar organic solvents like acetone or methanol at room temperature. It is insoluble in pure hydrocarbons.
  • POLYGLYKOL D 21/700 displays a very low solidification point of –35°C and no evaporation loss even at temperatures as high as 100°C. The hygroscopy of polyglycols increase with the EO ratio in the polymer.
