Cellulose nitrate is a white fibrous polymer that is resistant to water, dilute acids, weak alkalis and various oils. Insoluble in water, soluble in acetone, ethyl ether ethanol mixture. Easy to change color under the sun, extremely flammable, smoke-free, instant release of a lot of gas. Different degrees of polymerization, its strength is also different, but are thermoplastic materials. It changes color easily in sunlight and burns easily. In the production and processing, packaging, storage and transportation, sales, use should pay attention to safety.
