● Product Description
Poly(L-lactide) (PLLA) is a a biodegradable and biocompatible polymer derived from renewable lactic acid sources.
It is widely used in medical, pharmaceutical, and industrial applications due to its high tensile strength, thermal stability, and controlled degradation properties. With excellent mechanical performance, PLLA is an ideal material for absorbable sutures, orthopedic implants, drug delivery systems, and tissue engineering scaffolds. In industrial applications.
Our PLLA is available in different molecular weights to meet specific application requirements, ensuring optimal performance in processing techniques such as extrusion, injection molding, and electrospinning.
