Application of nitrocellulose Nitrocellulose, also known as cellulose nitrate or nitrocellulose, is an organic polymer compound with the chemical formula (C6H7N3O11) n. It is the product of the esterification reaction between cellulose and nitrate, usually in the form of white or slightly yellow cotton fluff, insoluble in water, but soluble in organic solvents such as esters and acetone Nitrocellulose, also known as cellulose nitrate ester, abbreviated as NC, commonly known as nitrocellulose, is the product of the reaction between cellulose and nitrate. Nitrocellulose made from cotton fibers is called nitrocellulose. Nitrocellulose is a white fibrous polymer that is resistant to water, dilute acids, weak alkalis, and various oils. Different degrees of polymerization result in different strengths, but they are all thermoplastic substances. Easy to change color under sunlight and highly flammable. Attention should be paid to safety in production, processing, packaging, storage, transportation, sales, and use.
