BP10959 OH-PDLLA-COOR, High Molecular Weight Grades (IV ≥ 1.5 dl/g, Mw ≥ 280 kDa)

OH-PDLLA-COOR, high molecular weight polymer, ester-terminated, ultra-high Mw polymer, engineering bioplastic, high-strength biodegradable polymer, extrusion grade, injection moulding grade, ≥ 280 kDa, ≥ 1.5 dl/g

OH-PDLLA-COOR, High Molecular Weight Grades Description

OH-PDLLA-COOR (High Mw Grade) is an ultra-high molecular weight, ester-capped biodegradable polymer designed to meet the most demanding mechanical and durability requirements. With intrinsic viscosity ≥ 1.5 dl/g and molecular weights extending to 1900 kDa, it rivals conventional engineering plastics in performance while remaining fully biodegradable. Its pellet or powder form ensures compatibility with standard industrial polymer processing, making it a viable sustainable alternative for durable applications.

OH-PDLLA-COOR, High Molecular Weight Grades Applications

1.         High-Performance Films, Sheets & Profiles
- Heavy-Duty and Agricultural Films: Manufacture high-strength mulch films, greenhouse covers, or silage wraps that must withstand prolonged UV exposure and mechanical stress for multiple seasons before degrading.
- Extruded Structural Profiles: Produce robust profiles for temporary fencing, horticultural supports, or compostable composite decking components.

2.         Durable Moulded and Thermoformed Articles
- Injection Moulded Industrial Components: Fabricate high-strength parts such as pallets, shipping totes, tool handles, or automotive interior components designed for a multi-year service life with controlled end-of-life.
- Thermoformed Packaging and Trays: Create rigid, durable packaging for heavy items or electronics that require structural protection during use and shipping.

3.         Advanced Processing and Composites
- Foams and Lightweight Cores: Utilise its high melt strength for producing biodegradable foams for packaging, insulation, or composite core materials.
- Matrix for High-Loading Composites: Act as a tough matrix in composites with high filler loadings (e.g., wood flour, mineral fillers) for applications such as biodegradable furniture or construction elements.

Additional Information

This high molecular weight ester-terminated grade represents the apex of mechanically performant biodegradable polyesters. It effectively decouples the traditional link between biodegradability and low mechanical strength, opening doors for sustainable materials in markets traditionally dominated by PP, ABS, or HDPE. Its ester end-group ensures processing reliability and shelf stability that is critical for industrial adoption. SAM provides technical support, including detailed rheological data, mechanical property profiles, and application development guidance to facilitate the successful integration of this high-performance material into demanding product designs.
