Product data sheet
微球 (PDLLA Microspheres)
Description
With the great efforts of our talented and diligent R&D team, we not only could produce the PDLLA polymers, but also the PDLLA microspheres from 5μm to 25μm. Because of good biocompatibility and biodegradability, they can be used in various areas, such as for plastic surgery implants, dermal fillers and other high-end anti-aging cosmetic products.
