Cellulose esters

Cellulose esters are produced from wood cellulose. They are therefore partially biobased, but are generally not biodegradable (except in the form of regenerated pulp).

Depending on the chemical modifications made, different materials can be obtained, such as cellulose acetate or cellulose proprionate. This family of materials is highly transparent, with good mechanical and thermal properties. They are used, for example, in injection molding processes, or in the machining of sheets for the manufacture of spectacle temples.
