polycaprolactone

Polycaprolactone (PCL) is a synthetic aliphatic polyester known for its low melting point, semi-crystalline structure, and excellent processability via conventional thermoplastic techniques. It is widely used in biomedical devices, packaging, and 3D printing applications where biodegradability, flexibility, and ease of fabrication are valued—particularly in orthopedic fixation devices, drug delivery systems, tissue engineering scaffolds, and consumer products where disposal or resorption in the body is desirable. Engineers select PCL over commodity plastics when end-of-life biodegradation is required or when controlled material degradation is part of the design specification.
