Polycaprolactone (PCL) Services
Polycaprolactone (PCL) is a synthetic linear aliphatic polyester. It is typically obtained through the ring-opening polymerization of ε-caprolactone monomers and is a semi-crystalline polymer. Initially, PCL was primarily studied as a biodegradable plastic material. In recent years, due to its biodegradability, excellent biocompatibility, tunable mechanical properties, and ease of blending with other polymers, it has become an important candidate in biomimetic material research. BOC Sciences has long focused on the custom synthesis, modification, and analysis of polymer chemicals and monomers, providing high-quality PCL products and technical support for customers engaged in biomimetic material research, development, and production. Through tailored solutions, we help research institutions, pharmaceutical companies, and material developers achieve breakthroughs in cutting-edge applications.
