Category overview
Polyglycolic Acid is a biodegradable aliphatic polyester known for its exceptional mechanical strength, high crystallinity providing excellent gas barrier properties, biocompatibility with human tissue, and good thermal stability with a relatively high melting point. PGA is primarily used in surgical sutures, tissue engineering scaffolds, drug delivery systems, food packaging requiring, oil and gas industry, and as reinforcement in other biodegradable polymer systems.
Alternatives include polylactic acid (PLA) and polycaprolactone (PCL). Current trends in PGA technology focus on expanding its application range beyond high-value medical uses through cost reduction, developing copolymers with modified degradation profiles, and creating composite materials that maintain biodegradability while addressing PGA's inherent brittleness. Major sub-types include high molecular weight PGA, copolymers such as poly(glycolide-co-lactide) or PLGA, and various blends with other biodegradable polymers.
