 | The viscosity of Walsroder Nitrocellulose or Walsroder NC-Chips depends on the molar mass (molecular weight) of the nitrocellulose. As determining the molar mass is far more complex than determining the viscosity, and as the viscosity of the solution is significant in practical terms, a viscosity index is stated and the viscosity of the nitrocellulose in a specific solvent mixture is specified.
The viscosity of the individual nitrocellulose grades available from Wolff Cellulosics is determined by the Cochius method. To compare the viscosity of nitrocellulose from various suppliers, ISO 14446 is a useful standard to follow.
