PCL, poly(ɛ-caprolactone), Carboxyl-Terminated, IV: 3.0–4.0 dl/g, Mw: 526–790 kDa Description

PCL, poly(ɛ‑caprolactone) is a semi-crystalline aliphatic polyester produced via ring-opening polymerisation of ɛ‑caprolactone. The carboxyl‑terminated structure allows for further chemical modification and chain extension reactions. The specified intrinsic viscosity informs about the average molecular weight, crucial for tuning mechanical strength and degradation behaviour in biomedical and industrial prototype settings. Its well-defined molecular range facilitates reproducible processing outcomes.

It is stored in a cool, dry environment away from direct sunlight to preserve its polymer characteristics. Custom packaging solutions, including vacuum-sealed or inert gas-flushed options, are available to meet specific storage and processing requirements.

Additional Information

PCL (polycaprolactone) is a biodegradable polyester extensively studied in the field of biocompatible materials. Its controlled degradation and ease of processing make it a valuable material for biomedical applications such as tissue scaffolding and drug delivery systems. Understanding the relationship between molecular weight and intrinsic viscosity is critical for tailoring its performance.

The carboxyl termination enhances the polymer's aqueous dispersibility and provides active sites for further chemical modification, thereby improving its compatibility with hydrophilic matrices and facilitating ionic interaction or covalent grafting within composite systems. This expands the material's applicability in advanced manufacturing and functional biomaterial design. Ongoing research continues to refine processing techniques to optimise performance and reliability across diverse applications.
