PLGA-di-amine, MW 30K

PLGA-di-amine, MW 30K is a medium-to-high molecular weight linear biodegradable polyester capped with symmetrical primary amine groups at both chain ends. Synthesized via controlled copolymerization of D,L-lactide and glycolide, this grade supports all standard LA/GA ratios (50:50, 65:35, 75:25, 85:15) as well as fully customized monomer proportions. Positioned between 20K and 40K specifications, the 30K PLGA-di-amine features extended molecular chains, moderate mechanical toughness, and a medium-slow degradation rate, filling the performance gap between conventional long-acting and ultra-stable PLGA derivatives. Its dual-terminal amine groups retain excellent nucleophilic activity, enabling efficient covalent crosslinking, protein conjugation, and block copolymer synthesis. The material exhibits superior solution stability and particle forming performance, while its degradation byproducts are fully biocompatible and metabolizable in biological systems. This grade is ideal for medium-long term sustained-release formulations, high-stability polymeric nanoparticles, and robust hydrogel platforms that require balanced mechanical performance and predictable degradation behavior.
