Poly(ethylene glycol)-block-Poly(lactic acid) (PEG-b-PLA)

Product Overview
Poly(ethylene glycol)-block-Poly(lactic acid) (PEG-b-PLA) is a block copolymer synthesized through the copolymerization of polyethylene glycol (PEG) and polylactic acid (PLA). This copolymer exhibits excellent biocompatibility and biodegradability, with an adjustable molecular weight tailored to meet specific application needs. PEG-b-PLA is widely used in drug delivery systems, medical imaging, and biodegradable medical devices. It complies with the YY/T 0661-2008 standard, ensuring minimal heavy metals, low tin residue, and low sulfate ash content.
