Polyglycolic acid (PGA)

Description

1. Product Overview
   Polyglycolic acid (PGA) is a high-performance, biodegradable aliphatic polyester derived from the polymerization of glycolide. It is widely recognized for its exceptional mechanical strength, high barrier properties, and rapid biodegradation profile under hydrolytic conditions. In industrial and biomedical sectors, PGA plays a critical role in applications requiring temporary structural integrity followed by controlled degradation. Its strategic importance continues to grow as global industries shift toward sustainable, high-value advanced materials that reduce long-term environmental impact while maintaining superior performance standards.
2. Key Specifications & Technical Characteristics
