Chemical Structure:
Product Features and Applications: PLGA is an atactic copolymer and an amorphous polymer. Compared to PLA, the degradation time of the polymer can be controlled according to the GA content, offering softness and elasticity. Different monomer ratios can produce various types of PLGA, such as PLGA 75:25, indicating the polymer is composed of 75% lactic acid and 25% glycolic acid. The degree of PLGA degradation varies with the monomer ratio, with a higher lactide content leading to easier degradation.
