Polycaprolactone (PCL) is a synthetic aliphatic polyester with a low melting point and semi-crystalline structure, commonly used as a homo- or copolymer in medical devices, packaging, and additive manufacturing. It is valued in biomedical applications for its biocompatibility and biodegradability, particularly where controlled degradation over months to years is required. PCL is also popular in 3D printing and as a plasticizer or blend component because of its processability and ability to impart flexibility; it serves as a lower-cost alternative to more hydrolytically unstable polyesters in non-critical applications.
