Product Properties
  • POLYGLYKOL D 21/300 is a clear neutral viscous liquid at room temperature. POLYGLYKOL D 21/300 is soluble in water and polar organic solvents like acetone or methanol at room temperature. It is insoluble in pure hydrocarbons.
  • POLYGLYKOL D 21/300 displays a very low solidification point of –38°C and no evaporation loss even at temperatures as high as 100°C.
  • The viscosity of POLYGLYKOL D 21/300 corresponds to ISO VG 460 class. The hygroscopy of polyglycols increase with the EO ratio in the polymer.
