FAQ

Frequently Asked Questions

Pyroxylin is the main chemical component of celluloid. Celluloid is pyroxylin plasticized with camphor.

Its use is very limited due to its high flammability. It has been replaced by safer plastics, though it may be found in some specialty lacquers or in conservation of historical objects.

It is extremely flammable and can ignite or explode easily. It also degrades over time, releasing acidic gases.

It was used in early photographic and cinematic film (celluloid), in lacquers (e.g., for cars and furniture), in some early plastics for items like combs and toys, and in guncotton for explosives.

A highly flammable compound made by treating cellulose with nitric and sulphuric acids.
