Product Description

Product Description:

Polylactic acid (PDLA) is a type of biodegradable material known for its excellent bioabsorbability and biocompatibility. In the body, the degradation of poly (d-lactide) can be separated into two stages.
First, the lactic acid monomer undergoes hydrolysis, breaking down into lactic acid. Then, with the help of lactate dehydrogenase, the lactic acid is converted into pyruvate which enters the mitochondria and undergoes complete oxidation and decomposition, producing carbon dioxide and water as by-products.
Products made from poly (d-lactide) exhibit strong biocompatibility. They are metabolized and eliminated from the body without causing any harm or toxic effects. These products have a variety of biomedical applications such as being used as packaging agents for controlled and sustained drug release, tissue engineering scaffolds, materials for bone fixation and repair, microcapsules for injection, microspheres, implants, and elastomers for animal organs.
