 | A further grading feature of Walsroder Nitrocellulose and Walsroder NC-Chips is its damping agent content and the type of damping agent. Industrial nitrocellulose is required by law to contain at least 25% damping agent (e.g. alcohol, water) or 18% plasticiser.
The purpose of damping agents or plasticisers is to phlegmatise or stabilise the nitrocellulose in order to deactivate the hazardous properties of dry nitrocellulose (high flammability, high burning rates). The nitrocellulose grades offered by Dow Wolff Cellulosics are damped with at least 30% alcohol or water, or in the case of NC-Chips phlegmatised with 20% plasticiser.
The difference between Walsroder Nitrocellulose and Walsroder NC-Chips is the type of phlegmatizer used (alcohol or plasticizer). The noticeable difference is only their physical form and the method of handling them. Within the mean viscosity indicated, the nitrocellulose in both Walsroder Nitrocellulose and Walsroder NC-Chips is the same.
