• Elongation at Break: Elongation at break indicates the ductility of a material-the ability to stretch without breaking. CO₂-derived polymers generally demonstrate good elongation properties, which are essential for applications requiring flexibility. For example, polycarbonate-based CO₂ polymers can be tailored for use in flexible packaging or medical devices. Compared to conventional biodegradable plastics, some CO₂-based polymers show superior elongation characteristics, making them ideal for stretchable materials .
