Cellulose-based plastics, particularly cellulose nitrate and acetates, were the most commercially important semi-synthetics up to the 1940s and were used as the base for photographic film, textile fibres, moulded goods and in lacquers. Naturally occurring polymer cellulose in the form of cotton linters or wood pulp is chemically treated to increase its solubility. Cellulose has a high molecular weight of between 100000 and 500000 and an empirical formula C0H1OO5. Casein-formaldehyde is the only protein-based moulded plastic that achieved commercial success. It is based on cow s milk and is still produced in very small quantities for specialist items such as hand-coloured buttons. [Pg.40]

Oxidation in the presence of light has caused a casein-formaldehyde fork handle from the 1940s to craze, crack, shrink and discolour. [Pg.175]

Casein-formaldehyde soon was being produced and utilized in numerous applications across Europe. By 1915 European manufacturers of casein had found a viable method of making high-quality casein plastic. Dry casein could be slightly moistened with water, then processed into a plastic by... [Pg.10]
