High Flexibility Polycaprolactone Polymer NMPA Injectable Dermal Filler

2. Key Product Performance

• Superior Flexibility & Ductility: PCL is a semi-crystalline aliphatic polyester with ultra-low glass transition temperature. It maintains soft and tough physical properties at room and body temperature, featuring excellent flexibility and tensile ductility. Unlike rigid polymer materials, it can adapt to human skin and tissue stretching without hardening or foreign body sensation, ensuring comfortable and natural application effect.
• Controllable Slow Degradability: The material possesses stable and uniform hydrolysis performance. It degrades slowly and evenly in physiological environments through ester bond hydrolysis, avoiding rapid volume loss or local collapse. The complete degradation cycle is moderate and predictable, perfectly matching the cycle of human tissue repair and collagen regeneration.
• Excellent Biocompatibility & Safety: Medical-grade PCL has ultra-high purity with no toxic monomers or harmful residues. It will not cause immune rejection, inflammation or allergic reactions after implantation. The final degradation products are carbon dioxide and water, which can be completely metabolized by the human body, meeting strict medical safety standards.
• Outstanding Processability & Compatibility: With low melting point and good fluidity, PCL is suitable for microsphere preparation, electrospinning and injection molding. It can be perfectly blended with PLLA, HA and other materials to adjust hardness and degradation speed, meeting diversified customization needs for medical aesthetic fillers and tissue engineering materials.
