BP10989 PLGA 50:50, Hydroxyl Terminated, IV ≥ 0.55 dl/g, Mw ≥ 70 kDa

PLGA 50:50, Hydroxyl Terminated, IV ≥ 0.55 dl/g, Mw ≥ 70 kDa Description

BP10989 is a hydroxyl-terminated PLGA 50:50 copolymer with a high molecular weight (Mw ≥ 70 kDa) and correspondingly high intrinsic viscosity (IV ≥ 0.55 dl/g). The terminal hydroxyl group differentiates it by imparting a degree of hydrophilicity and chemical reactivity not found in ester-terminated grades. While the long polymer chains ensure slow degradation and mechanical properties, the hydroxyl functionality provides a site for further chemical modification, enabling the material to be tailored for specific high-performance and sustainable applications.

PLGA 50:50, Hydroxyl Terminated, IV ≥ 0.55 dl/g, Mw ≥ 70 kDa Applications

1.         High-Performance Biodegradable Composites
- Serves as a high-strength, bio-based matrix for advanced composites (e.g., with natural fibres, glass fibres), where the hydroxyl groups can improve interfacial bonding with polar reinforcing materials.
- Used in the manufacture of durable, compostable products for automotive, sporting goods, or construction that require extended service life and end-of-life controllability.

2.         Advanced Functional Coatings & Adhesives
- Acts as a base polymer for high-solids, environmentally friendly coatings and structural adhesives, benefiting from its strong film-forming ability and the potential for cross-linking via the hydroxyl group to enhance chemical resistance and durability.
- Applied in long-lasting protective coatings for infrastructure, where slow degradation and the option for chemical functionalisation are advantageous.

3.         Macromolecular Building Block for Chemical Synthesis
- Utilised as a macroinitiator or prepolymer for synthesising well-defined block copolymers, graft polymers, or complex polymer networks through reactions at the hydroxyl terminus.
- A key raw material in research and development of novel biodegradable polymers with customised architectures and properties for specialised industrial uses.

4.         Long-Term Controlled Release Systems
- Functions as the carrier polymer for the sustained release of active agents (e.g., agrochemicals, corrosion inhibitors, specialty additives) over periods of months to years, where its slow degradation profile and potential for surface modification are critical.

5.         Research & Material Development
- Serves as an exemplary high-Mw model for investigating the interplay between polymer architecture (including end-group chemistry), long-term degradation behaviour, and advanced processing techniques.
- A benchmark material for developing high-performance biodegradable materials across industrial sectors.
