PLGA Acid Capped 75:25 MW 10K is a high-molecular-weight carboxyl-terminated PLGA copolymer with a 75:25 lactide glycolide ratio, offering enhanced hydrophobicity, superior matrix rigidity, and slower, long-term biodegradation kinetics. Its terminal COOH functional groups remain highly active for precise bioconjugation while the higher molecular chain length significantly improves film-forming ability, particle structural integrity, and release sustainability. Unlike lower MW grades, 10K PLGA-COOH minimizes burst drug release and supports stable prolonged drug delivery over months. Ideal for manufacturing robust PLGA microspheres, long-acting sustained-release depots, durable polymer scaffolds, and high-stability conjugated drug carriers. Fully biocompatible and metabolically safe, this high-molecular PLGA grade is widely adopted for advanced controlled-release pharmaceutical research and biomaterial engineering.
