BP10983 OH-PDLA-COOH, High Molecular Weight Grades, IV ≥ 3 dl/g, Mw ≥ 480 kDa

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

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

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

1.       Long-Term, High-Load Biomedical Implants & Devices
- Used as the primary structural polymer for long-term absorbable orthopedic fixation devices (e.g., bone plates, screws, anchors) and load-bearing surgical meshes designed for degradation over years.
- Serves as a high-strength matrix for tissue engineering scaffolds intended for the regeneration of load-bearing tissues such as bone and cartilage, providing long-term mechanical support

2.       Advanced Polymer Networks & High-Performance Composites
- Acts as a macromolecular cross-linker or building block for synthesising dense, high-strength biodegradable polymer networks (e.g., for polyurethanes or polyanhydrides) used in demanding structural applications.
- Utilised as a base polymer in stereocomplex PLA formulations to create composites with thermal stability and mechanical properties for durable yet biodegradable industrial prototypes or components.

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