Poly(glycolic acid) [i.v. 1.0-2.0]

Poly(glycolic acid) (PGA) is a biodegradable polyester with high crystallinity, excellent mechanical properties, and hydrolytic degradability. The intrinsic viscosity (i.v.) range of 1.0-2.0 suggests moderate to high molecular weight, influencing degradation rates and mechanical strength.
Decomposes in 6 months at 37° at pH 9.0.

Applications:

Biomedical Devices: Used in sutures, scaffolds, and drug delivery systems.
Packaging Films: Provides biodegradable alternatives for food packaging.
Engineering Plastics: Enhances toughness in polymer blends.
