 made by treating cellulose nitrate with camphor and alcohol. Celluloid was the first important synthetic plastic and was widely used as a substitute for more expensive substances, such as ivory, amber, horn, and tortoiseshell. It is highly flammable and has been largely superseded by newer plastics with more desirable properties. It has been used for combs, brush handles, billiard balls, knife handles, buttons, and other useful objects.

Celluloid

 

a plastic based on cellulose nitrate (pyroxylin). It also contains a plasticizer (dibutyl phthalate, castor oil, petrolatum, or synthetic camphor) and a dye. Celluloid is processed by hot stamping, pressing, and mechanical working. It is used in the manufacture of various products, including plane-table boards, rulers, certain haberdashery goods, and toys. Because Celluloid is highly flammable, there has been a considerable reduction in its use.
