PDLLA（外消旋聚乳酸）

全称为外消旋聚乳酸（Poly(D,L-lactide)），是一种由左旋乳酸（L-lactide）和右旋乳酸（D-lactide）两种异构体组成的无定形聚合物。

已经通外科植入标准检测，可用于医学领域如：药物控释、组织工程支架、骨固定及骨修复材料、注射用微胶囊、微球、埋植剂等材料。

1.具有良好的生物相容性，能够在体内与周围组织和谐共存，不引起不良反应。

2.具有优异的可降解性，能够在体内自然降解成乳酸，进一步代谢为二氧化碳和水，因此对人体无毒无害。其降解速度相对较慢，这使其在临床应用中能够提供更持久的疗效。

产品型号：

1. PDLLA

Poly(D,L-lactide) is an amorphous polymer composed of two isomers—L-lactide and D-lactide.It has met the standards for surgical implantation and can be used in medical applications.

Applications:

lDrug-controlled release,

lTissue engineering scaffolds,

lBone fixation and repair materials,

lInjectable microcapsules,

lMicrospheres,

lImplants

Key Features:

1. Excellent biocompatibility, ensuring compatibility with surrounding tissues without causing adverse reactions.

2. Controlled biodegradability—naturally degrades into lactic acid, which is further metabolized into carbon dioxide and water, ensuring safety for biomedical applications. Its relatively slow degradation rate enables prolonged efficacy in clinical applications.
