cellulose butyrate

Cellulose butyrate is a semi-synthetic polymer derived from cellulose that has been chemically modified through esterification with butyric acid, creating a thermoplastic material with improved processability compared to unmodified cellulose. It is used in applications requiring transparency, moderate rigidity, and good dimensional stability, particularly in optical components, safety glazing, and specialty films where its balance of clarity and toughness provides advantages over both rigid thermoplastics and more flexible alternatives. The material is valued in niche applications where the inherent biodegradability of its cellulose backbone and its ability to be molded at moderate temperatures offer cost or sustainability benefits over fully synthetic polymers.
