Polyglycolic acid (PGA) is a biodegradable polymer made from glycolic acid. It is commonly used in medical applications, particularly for sutures and tissue engineering, due to its ability to break down safely in the body over time. PGA is known for its strength and flexibility, making it suitable for various surgical procedures. In addition to its medical uses, PGA can also be found in other fields, such as biomaterials and drug delivery systems. Its biocompatibility and degradation properties make it an important material in developing innovative solutions for health and environmental challenges.
