Material	CA - cellulose acetate
	Cellulose acetate (CA) is used for transparent, translucent and opaque objects (e.g. typewriter keys, calculators, switches, car wheel coverings). Furthermore, it is especially suitable for coatings applications requiring high melting-point, toughness, clarity, and good resistance to ultraviolet light, chemicals, oils, and greases. Cellulose acetate is an amorphous thermoplastic material belonging to the cellulosic resin family. It is obtained by introducing the acetyl radical of acetic acid into cellulose (as cotton or wood fibres) to produce a tough plastic material.

Environmen- tal notes	Creation: Made from chemical modification of cellulose, which is one of the most diffuse organic substances in nature. Use: Cellulose acetate is inflammable and burns with a yellowish flame producing a smelling smoke. Additive are often used to decrease its inflammability and to give the material self-estinguishing properties.
Additional Info	First plastic to be injection moulded. Cellulose acetate becomes brittle at temperature under the freezing point. It is an insulator material and shows only a little tendency to electrostatic charging.
