Nitrocellulose itself is flammable and explosive dangerous goods, nitrocellulose highly the flammability and explosive, its dangerous degree depending on the degree of nitrification.Risk of nitrogen content in more than 12.5% of the maximum, in a fire that is burning. The outbreak of 180~185 degrees. Aqueous 25% safer. Can accelerate the decomposition andcombustion at temperatures above 40 DEG C, the detonation velocity of 6300m/s, the nitrogen content of less than 12.5% although relatively stable, but the heated or stored a long time, due to the gradual decomposition and release acid, reducing fire point, easy toget angry or the possibility of explosion. So, nitrocellulose itself is highly flammable, I know a NC processing factory, because sewing machine ignition, tens of millions of product packaging library on fire, fire engines are not down.
