Celluloid is a type of thermoplastic that was one of the first synthetic plastics.

Chinese name: Celluloid, Cloud Stone Film, Agate Film
English name: Celluloid Nitrate
Chinese name 2: Nitrocellulose Plastic
Appearance and properties: Colored or colorless transparent or opaque sheets, soft and elastic.
Melting point: 110℃
Relative density (water=1): 1.35~1.60
Ignition temperature: 180℃
Solubility: Insoluble in water, benzene, toluene, but soluble in ether.
Main uses: Mainly used to produce eyeglass frames, lenses, table tennis balls, sunglasses, toys, pen barrels, building decorations, etc.
Other physical and chemical properties: Above 75
Explosion hazard: This product is easily combustible.
Hazardous characteristics: Easily combustible at high temperatures. Long-term storage can gradually generate heat, and if not dissipated, it can self-ignite.

Production technology of celluloid

1. Nitrocellulose plastic with camphor as a plasticizer is processed into plastic products through thermal forming (for nitration).
The effect is to make the finished product very easy to burn.
2. By adding various pigments and additives, plastic sheets and boards with strong three-dimensionality are produced, while maintaining a certain degree of improvement in flammability, strength, durability, geometric stability, and other characteristics.

Characteristics
Celluloid is thinner and lighter than bakelite, becomes brittle when heated to higher temperatures, and can crack. Moreover, some cellulose burns easily, is more brittle than bakelite, but can be bent and twisted. When heated in water, most have a smell similar to vinegar and old camphor. Cellulose stored in a closed environment for a long time is also very dull and may have cracks.

Uses

The uses of cellulose are diverse, far exceeding the scope of billiard tables. It can be shaped at the boiling point of water, can be cut, drilled, and sawed at low temperatures. It can also be hard lumps or made into soft sheets (which can be used for shirt collars and children's toys, etc.). Thinner and tougher sheets can be used as a base for gel-like silver compounds, becoming the first practical photographic base.


Common uses include table tennis balls, jewelry headdresses, and instrument decorations. Other uses span various fields in the chemical industry, aerospace, machinery, dyeing, building materials, decoration, packaging, cosmetics, gift packaging, etc.
