PLGA Ester Capped (85:15), MW 20K is a biodegradable copolymer with an 85:15 lactide:glycolide ratio, ester end groups, and an approximate molecular weight of 20 kDa. Its lactide-rich composition specifically supports controlled drug delivery, particle formulation, and biomaterial development.
Key Features and Benefits
- Ester Capped: Provides ester end groups that reduce terminal carboxyl functionality.
- 85:15 PLGA Ratio: High lactide content supports slower water uptake and extended degradation compared with glycolide-rich PLGA compositions.
- MW 20K: Offers efficient polymer processing and versatile formulation properties.
- Biodegradable: PLGA hydrolyzes into lactic acid and glycolic acid under physiological conditions.
- Versatile Polymer: Supports particles, films, matrices, coatings, and other biodegradable delivery systems.
Applications
- Drug Delivery: Controls drug release through biodegradable polymer matrices.
- Long-Acting Formulations: Supports development of depots and other controlled-release systems.
- Microparticles: Forms biodegradable microspheres and related drug-loaded particles.
- Nanoparticles: Supports preparation of biodegradable polymeric nanoparticles and drug carriers.
- Biomaterials: Enables development of films, coatings, matrices, and other biodegradable materials.
Storage and Handling
- Storage: Store at –20 °C in a sealed, dry container.
- Handling: Protect from moisture and excessive heat to limit premature hydrolysis and polymer degradation.
