What is Polycaprolactone CAS 24980-41-4?

Polycaprolactone (PCL) is an environmentally friendly polyester that is both biocompatible and biodegradable. Its core advantages lie in its low melting point, ease of processing, and excellent shape memory properties. In applications, PCL is used in orthopedics to create lightweight, breathable medical splints to replace plaster casts; it is also a safe and flexible 3D printing material and is widely used in the manufacture of fully biodegradable packaging films and high-performance hot melt adhesives. As a green new material, PCL is gradually replacing traditional plastics in many industries.
