CA - Cellulosic acetate

Cellulosic acetate (CA) material is esters bio-based polymers. They are produced through reaction of cellulose with organic acids, anhydrides or acid chlorides. Cellulose acetate is one of the oldest bio-based polymers in the world. Due to its properties, thermoplastic CA is a promising biopolymer for replacing PS in certain foam applications.

CA is commonly used for producing writing instruments, glasses, tool and knife grips, profiles and pipes, electrical goods, etc.
