Polycaprolactone (PCL) Polymer
Premium Biodegradable Solutions
Polycaprolactone (PCL) Polymer is a highly versatile, semi-crystalline, and fully biodegradable aliphatic polyester. Renowned for its exceptional flexibility, low melting point, and remarkably slow degradation rate, PCL has become a cornerstone material in advanced biomedical and industrial applications. Whether you are developing long-term medical implants, engineering controlled drug delivery systems, scaffolding for tissue engineering, or innovating in the 3D printing space, our medical-grade PCL delivers the reliability and performance your project demands.
Key Applications of Polycaprolactone (PCL)
- Long-Term Implants: With a degradation time of up to 2–4 years, PCL is ideal for long-term resorbable sutures, bone fixation devices, and orthopedic implants that require sustained mechanical support.
- Drug Delivery Systems: The slow hydrolytic degradation of PCL allows for highly controlled, sustained, and localized release profiles for therapeutic agents and pharmaceuticals.
- Tissue Engineering: Highly biocompatible and easily processable, PCL serves as an excellent structural scaffold for cell growth, skin grafts, and regenerative medicine.
- 3D Printing & Additive Manufacturing: Boasting a low melting point (~60°C) and excellent melt-flow properties, PCL is a favorite for FDM 3D printing, shape-memory polymers, and rapid prototyping of medical devices.
Understanding Our PCL Grades: Intrinsic Viscosity (IV) & End Groups
Selecting the right Polycaprolactone grade is critical for your specific application. Our standard PCL products are Ester-terminated, providing excellent chemical stability and predictable reactivity. The primary differentiator between our grades is the Intrinsic Viscosity (IV), which directly correlates to the polymer's molecular weight:
