Polysciences Inc. Poly(D,L-Lactide), IV 0.2 dL/g, Ester Terminated, Powder
MSE Supplies offers polymer reagents from Polysciences Inc.
Product Overview
High-grade, suitable for biomedical research.
Supplied as micronized powder.
Poly(DL-lactide) (PDLLA) is an ubiquitous biodegradable polymer. It is typically used to fabricate medical devices that predictably degrade over months in physiological conditions. The well-researched release profile also allows for drug-release functionalization with calculable results. Owing to its extensive history, PDLLA is one of the most understood and affordable biodegradable polymers for medical devices today.
