Nitrocellulose :-
Molecular formula [C6H702(OH)3-r(ONO2)r]n
Main Physical and Chemical
Characteristic
Nitrocellulose is white floc and chip fiber, wish specific heat about 0.4 and relative density 1.65-1.67g/cm2, highly flammable, soluble in organic solvent such as ketone, ester, alcohol ether etc, sensitive to machinery impact when alcohol is lower. It can react with acid, alkali, oxidant and reluctant.
Technical Index
1.Appearance
White floc and chip fiber, no containing on visible foreign matters
2.Type and Specification
Based nitrogen content, nitrocellulose for dope falls into H and L. Type H is also called as alcohol as aster-soluble nitrocellulose, with nitrogen content 11.5-12.2%, while L grade nitrocellulose can also be named as alcohol-soluble nitrocellulose, with nitrogen content 10.7-11.4%.

Notice:
1. There is no water content test for water nitrocellulose. Once customers have special request for viscosity and others, we will decide after negotiation with them.
2. Damping agent: alcohol, IPA, dibutylphosphate etc, water.
Packing:
1. Nitrocellulose is packed in galvanized steel barrel (280 liters) lined with polythene film bag according to DOT-17H. Net weight is 100kg for per barrel.
2. Nitrocellulose for domestic is packed in composite fiber drum lined with polythene film bag. Net weight is 20-25kg per drum.
3. Nitrocellulose may also be packed in composite fiber drum lined with polythene film bag. Net weight is 30-35kg per drum.
Notice in storage and transportation:
1. Nitrocellulose should be stored and transported according to the state regulations of shipping and stored dangerous goods.
2. This product should be moved and carried carefully during the course of transportation. It must be placed in truck with canvas cover or cabin and avoid sunlight and moisture.
3. Touching acid, alkali, and greasy dirties is not allowed, mixing with inflammable, explosive substance is also forbidden.
4. The product should be piled in order in the special storehouse, which must be cool, ventilated, fire prevented and no tinder near it.
5. According to the temperature, package and humectants sort, this moisture content and stable degree should be check regularly during the storage. The inner package should be inverted regularly so that makes the humectants uniformity. The storage time can’t exceed one month
6. Fire-extinguishing agent: water
