Celluloid
Celluloid is the name of a class of compounds created from nitrocellulose and camphor, plus dyes and other agents, generally regarded to be the first thermoplastic it was first created in 1856. more...
Easily molded and shaped, there are suggestions that celluloid was first made as an ivory replacement. Celluloid is highly flammable and also easily decomposes, and is no longer widely used. Its most common use today is the table tennis ball.
Nitrocellulose
Nitrocellulose-based plastics slightly predate celluloid: collodion, invented in 1848 and used as a wound dressing and emulsion for photographic plates, dried to a celluloid-like film.
Alexander Parkes
The first celluloid as a bulk material for forming objects was made in 1856 in Birmingham England by Alexander Parkes, he was never able to see his invention reach full fruition. Parkes patented his discovery after realising that a solid residue remained after evaporation of the solvent from photographic collodion, he described it as a "hard, horny elastic and waterproof substance".
Parkes patented it as a clothing waterproof for woven fabrics in the same year. Later in 1862, Parkes showcased Parkesine at the Great Exhibition in London where he was awarded a bronze medal for his efforts. Cellulose nitrate was dissolved in a small measure of solvent, this was then heated and rolled on a purpose built machine which extracted a proportion of the solvent. Finally, the use of pressure or dyes completed the manufacturing process. In 1866, Parkes tried again with his invention and he created a company to manufacture and market Parkesine but this failed in 1868 after trying to cut costs to enable further manufacture.
