PLLA, or Polylactic Acid, is a biodegradable polymer derived from renewable resources such as corn starch or sugarcane. It belongs to a family of lactic acid-based polymers and is known for its ability to break down naturally within the body. Because it is biocompatible and non-toxic, PLLA is ideal for medical implants, drug delivery systems, and cosmetic treatments, where long-term effectiveness and gradual biodegradation are required.
The lactide portion of PLLA refers to the cyclic ester unit, which is a fundamental building block that gives the polymer its unique properties. Over time, PLLA naturally degrades into lactic acid, which is harmlessly absorbed and eliminated by the body. This makes PLLA a safe, sustainable, and non-invasive option for various applications in aesthetic medicine, regenerative medicine, and bone tissue repair.
| Description | PLLA is a biodegradable thermoplastic aliphatic polyester, it can be completely degraded in the body. The product is excreted by metabolism and it does not have harm and side effects on the human body. Therefore our products are currently widely used in the field of medical devices, such as absorbable sutures, tissue engineering scaffolds, orthopedics, skin filling; microspheres, nanoparticles for drug delivery, etc. | ||||
