Nitro Cellulose

Whatsapp Order

Nitro Cellulose is a highly flammable compound produced by nitrating cellulose through exposure to nitric acid and sulfuric acid. It is a versatile material widely used in coatings, lacquers, explosives, and propellants due to its film-forming properties and rapid drying capability. Nitro Cellulose is available in various grades depending on the nitrogen content and viscosity, making it suitable for industrial, commercial, and military applications.
