Poly-L-Lactic Acid (PLLA) CAS 26811-96-1 Product Introduction Poly-L-lactic acid, also called Poly(L-lactide) or PLLA, CAS 26811-96-1 , is a high-purity biodegradable polymer made from L-lactic acid. It belongs to the poly(α-hydroxy acid) family and offers excellent mechanical strength, controlled degradation rate, and non-toxic degradation products such as lactic acid, water, and carbon dioxide. PLLA is a semi-crystalline polymer with a melting point around 170–185 °C and a
