Polycaprolactone (PCL) is a semi-crystalline aliphatic polyester synthesized by ring-opening polymerization of ε-caprolactone, valued for its biodegradability and processability at moderate temperatures. It is widely used in biomedical applications—including sutures, drug delivery systems, and tissue engineering scaffolds—as well as in flexible films, adhesives, and 3D printing filaments, where its combination of low melting point, high elongation capability, and slow degradation in physiological environments makes it preferable to faster-degrading polymers like PGA or more rigid alternatives.
