EN71-2: 2006+A1:2007 Safety of Toys, Flammability
– General Requirements
The following materials should not be used in the manufacture of toys: celluloid (cellulose nitrate) and highly flammable solids. In addition, the sample shall not contain flammable gases, highly flammable liquids, flammable liquids, or flammable gels.
The process uses the nitric acid to convert the cellulose into cellulose nitrate and water:
2HNO3+ C6H10O5 → C6H8(NO2)2O5 + 2H2O
Main Uses of Cellulose Nitrate:
· Magician's "flash paper", sheets of paper or cloth made from nitrocellulose, which burn almost instantly, with a bright flash, and leave no ash.
· Nitrocellulose lacquer,
Other uses of Cellulose Nitrate:
Depending on the manufacturing process, Cellulose Nitrate is esterified to varying degrees.
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. Celluloid is easily molded and shaped, and there are suggestions that it 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.
Paper is a commodity of thin material produced by the amalgamation of fibers, typically vegetable fibers composed of cellulose, which are subsequently held together by hydrogen bonding. While the fibres used are usually natural in origin, a wide variety of synthetic fibers, such as polypropylene and polyethylene, may be incorporated into paper as a way of imparting desirable physical properties.
