Poly(L-lactide) (PLLA)(CAT: M440060) is a semi-crystalline, biodegradable polymer derived from the L-isomer of lactic acid. Known for its high tensile strength, stiffness, and slow degradation profile, PLLA is widely applied in long-term biomedical devices and tissue engineering. Compared with amorphous PDLLA, PLLA provides superior mechanical stability, making it ideal for load-bearing applications such as orthopedic fixation devices, resorbable sutures, and cardiovascular scaffolds. Its degradation results in biocompatible lactic acid, naturally metabolized by the body. With tunable crystallinity and molecular weight, PLLA remains a cornerstone material in developing advanced bioresorbable implants, regenerative medicine scaffolds, and controlled drug delivery systems.
