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.
Note
  • Typical Properties are for guidance only and not to be taken as product specifications. The tolerances are given in the product specification sheet.
  • * Contact angle of water on V2A steel: 64°.
  • ** Surface tension of water: 71.6 mN/m.
  • ¹ - n:m = 2:1.
