BP10958 OH-PDLLA-COOR, Medium Molecular Weight Grades (IV 0.3-1.5 dl/g, Mw 30-280 kDa)

OH-PDLLA-COOR, Medium Molecular Weight Grades Description

OH-PDLLA-COOR (Medium Mw Grade) is a versatile, ester-capped biodegradable polymer covering a practical range of molecular weights (30–280 kDa). Engineered to bridge the gap between easy processing and functional performance, it is an ideal choice for manufacturing durable yet degradable films, fibres, injection-moulded articles, and composite materials. Its consistent granule or powder form ensures reliable feeding and dispersion in both melt and solution-based processes.

OH-PDLLA-COOR, Medium Molecular Weight Grades Applications

1.       Films, Fibres & Moulded Articles
   - Blown/Cast Films: Produce controlled-lifespan packaging films, agricultural mulch films, or compostable bags.
   - Monofilaments & Fibres: Extrude into fibres for non-woven fabrics, horticultural twines, or reinforcing elements in composites.
   - Injection/Compression Moulded Parts: Manufacture disposable cutlery, plant pots, or other single-use items designed for biodegradation.

2.       Coatings & Compound Modifications
   - Protective & Functional Coatings: Apply via solution or melt as a degradable coating on paper, cardboard, or other substrates to provide temporary barrier properties.
   - Polymer Blend Component: Use as a base resin or modifier in compound formulations to adjust melt flow, flexibility, or degradation rate of the final product.

3.       Green Composites & Additive Manufacturing
   - Matrix for Natural Fibre Composites: Act as the biodegradable polymer matrix in composites reinforced with wood flour, hemp, or other natural fibres.
   - Feedstock for Fused Deposition Modelling (FDM): Formulate into filaments for 3D printing of prototypes or end-use parts with defined degradation profiles.

Additional Information

The medium molecular weight ester-terminated PDLLA is a  cornerstone material for the biodegradable plastics industry. Its balanced property set makes it a go-to choice for converters and compounders developing products that must meet both performance specifications and environmental end-of-life criteria. Understanding the interplay between IV (processability), Mw (mechanical properties), and the stable ester end-group (shelf life) is key to successful application development.
