BP10965 OH-PDLLA-COOH, High Molecular Weight Grades (IV ≥ 1.5 dl/g, Mw ≥ 280 kDa)

OH-PDLLA-COOH, High Molecular Weight Grades Description

OH-PDLLA-COOH (High Mw Grade) is an engineering-grade, functionalised biodegradable polymer. With intrinsic viscosity ≥ 1.5 dl/g and molecular weight ≥ 280 kDa, it is designed for applications demanding the mechanical performance of conventional plastics combined with end-of-life biodegradability and a reactive handle for advanced material design. Its granule or pellet form ensures reliable feeding in industrial melt-processing equipment.

OH-PDLLA-COOH, High Molecular Weight Grades Applications

1.         High-Strength Engineered Articles
- Injection Molded Structural Parts: Manufacture durable components such as brackets, housings, or tooling for temporary use in automotive, electronics (e.g., shipping fixtures), or consumer goods, where strength and controlled degradation are required.
- Extruded Profiles & Sheets: Produce heavy-duty films, sheets for thermoforming, or profiles for agricultural or construction applications that need to withstand environmental stress for a defined period.

2.         Advanced Composites & Bonding Layers
- Matrix for High-Performance Composites: Serve as a strong, degradable matrix for composites reinforced with continuous natural or synthetic fibres, targeting semi-structural applications.
- Reactive Adhesive/Tie Layer: Utilise the carboxyl functionality to create chemically bonded interfaces in multi-layer films or co-extruded structures, improving delamination resistance.

3.         Specialty Fibres & 3D Printing
- High-Tenacity Fibres: Spin into monofilaments or multifilament yarns for technical textiles, geotextiles, or sutures/industrial sewing threads that require high strength and slow degradation.
- FDM 3D Printing Filament: Formulate into filaments for printing robust, functional prototypes or end-use parts with complex geometries and engineered degradation properties.

Additional Information

This high molecular weight carboxyl-terminated grade pushes the boundaries of biodegradable polymer performance. It challenges the notion that biodegradable materials are inherently weak, offering a pathway to replace certain conventional plastics in durable goods. The retained carboxyl functionality is a key differentiator, enabling covalent integration into advanced material systems that pure polyolefins cannot achieve. SAM provides technical data on rheology, mechanical properties, and recommended processing windows to support the adoption of this high-performance biopolymer in innovative and demanding applications.
