BP10962 OH-PDLLA-OH, High Molecular Weight Grades (IV ≥ 1.5 dl/g, Mw ≥ 280 kDa)

OH-PDLLA-OH, High Molecular Weight Grades Description

OH-PDLLA-OH (High Mw Grade) is an engineering-grade, reactive biodegradable polymer. With intrinsic viscosity ≥ 1.5 dl/g and molecular weight ≥ 280 kDa, it is designed to meet the mechanical demands of structural applications while providing the chemical functionality for advanced material design. Its granule or pellet form ensures compatibility with industrial polymer processing, bridging the gap between high-performance and sustainable material solutions.

OH-PDLLA-OH, High Molecular Weight Grades Applications

1.         Structural & Durable Biodegradable Articles
- Injection Molded Structural Components: Manufacture high-strength parts such as automotive interior clips, electronic housings, or industrial fixtures intended for temporary use, where durability and eventual breakdown are required.
- Extruded Profiles and Heavy-Duty Films: Produce strong sheets for thermoforming, protective barriers, or profiles for agricultural and construction applications that must withstand mechanical stress over a defined multi-year period.

2.         Advanced Reactive Composites & Coatings
- Matrix for High-Performance Composites: Serve as a strong, degradable matrix in composites reinforced with continuous fibres (e.g., glass, natural fibres) for semi-structural applications, with hydroxyl groups enhancing fibre-matrix adhesion.
- Cross-linkable Coating or Adhesive Base: Formulate into high-performance coatings or adhesives that can be chemically cured (e.g., with isocyanates, epoxies) for enhanced chemical resistance and bond strength on various substrates.

3.         Specialised Polymer Synthesis & Additive Manufacturing
- Macro-initiator for High-Mw Block Copolymers: Use as a difunctional initiator to synthesise very high molecular weight triblock or multi-block copolymers with unique thermomechanical properties.
- High-Strength 3D Printing Filament: Compound into filaments for Fused Deposition Modelling (FDM) to print durable, functional prototypes or end-use parts with complex geometries and engineered degradation.
