BP10988 PLGA 50:50, Hydroxyl Terminated, IV: 0.18–0.55 dl/g, Mw: 15–70 kDa

PLGA 50:50, Hydroxyl Terminated, IV: 0.18–0.55 dl/g, Mw: 15–70 kDa Description

BP10988 is a hydroxyl-terminated PLGA 50:50 copolymer within a medium molecular weight range (Mw: 15–70 kDa) and corresponding intrinsic viscosity range (IV: 0.18–0.55 dl/g). The terminal hydroxyl group defines its character, imparting enhanced hydrophilicity and aqueous compatibility compared to ester-capped variants. This functional group also serves as a versatile anchor point for chemical reactions, enabling covalent modification and integration into complex materials. This combination of mechanical properties, processability, and synthetic versatility makes it a valuable material for industrial and sustainable applications.

PLGA 50:50, Hydroxyl Terminated, IV: 0.18–0.55 dl/g, Mw: 15–70 kDa Applications

Industrial Formulations & Advanced Composites
- Functions as a bio-based binder or toughening agent in cellulose- or natural fibre-reinforced composites, where its hydroxyl groups improve interfacial adhesion to polar fibres.
- Used in formulations for biodegradable engineering plastics that require a balance of strength, processability, and compatibility with hydrophilic additives.

Functional Coatings & Adhesives
- Serves as a base polymer for environmentally friendly coatings and adhesives designed for polar substrates (e.g., paper, wood, metals with oxide layers), benefiting from its enhanced wetting and adhesion properties.
- Applied in the development of responsive or smart coatings where the hydroxyl group can be utilised for further functionalisation.

Sustained-Release Systems for Hydrophilic Actives
- Acts as a carrier matrix for the controlled release of hydrophilic active ingredients (e.g., certain agrochemicals, nutrients, or personal care actives) over an intermediate timeframe (weeks to months).
- Used to fabricate microspheres or devices where its degradation profile and affinity for aqueous environments are advantageous.

Chemical Synthesis & Material Development
- Acts as a macroinitiator or macromonomer for synthesising block or graft copolymers with tailored amphiphilicity or functionality.
- Serves as a key building block in research to develop novel biodegradable polymers, polymer conjugates, or cross-linked networks.

Research & Product Development
- Used as a model system to investigate the effects of molecular weight and hydrophilic end groups on mechanical properties, degradation kinetics, and release behaviour.
- A foundational material for prototyping biodegradable products in industrial and consumer goods.

Additional Information

The hydroxyl termination fundamentally shifts the property profile of this medium-Mw PLGA towards hydrophilicity and chemical reactivity, distinguishing it from standard ester-terminated grades. This opens specific application avenues in water-compatible systems and as a versatile platform for chemical innovation in material science.
