BP10980 OH-PDLA-OH, High Molecular Weight Grades, IV ≥ 3 dl/g, Mw ≥ 480 kDa

OH-PDLA-OH, High Molecular Weight Grades, IV ≥ 3 dl/g, Mw ≥ 480 kDa Description

OH-PDLA-OH (High Mw Grade) is a symmetrical, dihydroxy-terminated poly(D-lactic acid) with a molecular weight ≥ 480 kDa and intrinsic viscosity ≥ 3 dl/g. Its long polymer chains provide high mechanical strength and a slow, predictable degradation profile, making it suitable for long-term applications. The dual hydroxyl end groups offer reactivity for chemical modification and network formation, while the D-configured backbone enables valuable stereocomplexation with PLLA. This material is engineered for use in scenarios where durability, structural performance, and controlled biodegradability are required over an extended period.

OH-PDLA-OH, High Molecular Weight Grades, IV ≥ 3 dl/g, Mw ≥ 480 kDa Applications

1.       Long-Term Medical Implants & High-Load Scaffolds
   - Used in the manufacture of absorbable orthopedic fixation devices (e.g., bone plates, screws) and surgical meshes designed for degradation over several months to years.
   - Serves as a structural matrix for high-strength tissue engineering scaffolds intended for the regeneration of load-bearing tissues such as bone and cartilage.

2.       Durable Biodegradable Networks & Composites
   - Acts as a macro-cross-linker or building block for synthesising strong, covalently cross-linked polymer networks (e.g., for biodegradable polyurethanes or polyesters) used in demanding applications.
   - Utilised as a base polymer in stereocomplex PLA formulations to create composites with enhanced thermal and mechanical properties for durable yet biodegradable industrial components or prototypes.

3.       Controlled Release Systems & Functional Materials
   - Functions as a carrier matrix for drug delivery systems designed for sustained release over extended periods (months to years).
   - Applied in the development of high-performance, biodegradable coatings, films, or adhesives where long-term environmental stability followed by eventual degradation is desired.
