The first celluloids were made in 1856 by Alexander Parkes , but he was never able to actually use his invention. The name Celluloid actually began as a trademark of the Celluloid Manufacturing Company, which manufactured the celluloids patented by John Wesley Hyatt (whose use of heat and pressure simplified the manufacture of these compounds). The name was registered in 1870.
In the late 1880s, celluloids for photographic film were developed. Hannibal Goodwin and the Eastman Company both obtained patents for a film product; but Goodwin, and the interests he later sold his patents to, were eventually successful in a patent infringement suit against the Eastman Kodak Company. Nevertheless, the groundwork in these products was set for a photographic film, as opposed to a photographic plate, with all the implications that has for motion pictures.
As thermoplastics, celluloids found a wide variety of uses in the 19th and the first half of the 20th century. Things like knife handles, fountain pen bodies, collars and cuffs, toys, etc were made of this material. However, it burned easily and suffered from spontaneous decomposition, and was largely replaced by cellulose acetate plastics and later polyethylenes by the middle of the 20th century. The use of celluloid for early film however has caused large problems in film preservation.
A typical formulation of celluloid might contain 70 to 80 parts nitrocellulose, nitrated to 11% nitrogenNitrogen is the chemical element in the periodic table that has the symbol N and atomic number 7. A common normally colorless, odorless, tasteless and mostly inert diatomic non-metal gas, nitrogen constitutes 78 percent of Earth's atmosphere and is a cons, 30 parts camphor, 0 to 14 parts dyeA dye can generally be described as a coloured substance that has an affinity to the substrate to which it is being applied. The dye is usually used as an aqueous solution and may require a mordant to improve the fastness of the dye on the fibre. In contr, 1 to 5 parts ethyl alcohol, plus stabilizers and other agents to increase stability and reduce flammability.
One of the products still made from celluloid is the table tennisTable tennis also known as Ping-Pong (that name is trademarked), is the second most played sport in the world as well as the newest of the world's major sports. Ping pong ball is the official name for the sport in China. General description Play is on a n ball.
