Poly(L-lactic acid), SRU

Description:
Poly(L-lactic acid) (PLLA), with the CAS number 26161-42-2, is a biodegradable and biocompatible polymer derived from renewable resources, specifically from the fermentation of carbohydrates to produce lactic acid. It is a member of the polylactic acid family and is known for its excellent mechanical properties, including tensile strength and flexibility, making it suitable for various applications, particularly in the biomedical field. PLLA exhibits a glass transition temperature that allows it to maintain its structural integrity at physiological temperatures, and it degrades into non-toxic byproducts, primarily lactic acid, which can be metabolized by the body. The polymer is often used in drug delivery systems, sutures, and tissue engineering scaffolds due to its favorable degradation rate and compatibility with human tissues. Additionally, PLLA can be processed through various methods such as extrusion, injection molding, and 3D printing, allowing for versatile applications in both medical and environmental contexts. Its sustainability and biodegradability make it an attractive alternative to traditional petroleum-based plastics.
