Description

Lactide-Caprolactone Copolymer is a biodegradable, biocompatible aliphatic polyester with tunable mechanical and degradation properties. This copolymer is engineered to combine the characteristics of polylactide (PLA) and polycaprolactone (PCL), offering a versatile material platform for advanced applications. It is essential for industries requiring controlled-release systems, medical devices, and environmentally friendly materials.

Application

• Controlled Drug Delivery Systems: Used as a matrix for microspheres, nanoparticles, and implants for sustained release of active pharmaceutical ingredients (APIs).
• Biomedical Implants & Tissue Engineering: Serves as a scaffold material for bone regeneration, wound healing, and absorbable surgical sutures due to its biocompatibility and adjustable degradation rate.
• Specialty Adhesives & Coatings: Formulated into bio-based adhesives for medical applications and protective, degradable coatings for agricultural or packaging uses.
• 3D Printing Filaments: Utilized in fused deposition modeling (FDM) to create custom, biodegradable prototypes and medical models.
• Environmentally Friendly Plastics: Incorporated into polymer blends to enhance the flexibility and biodegradability of disposable products and packaging materials.

Quality Control

Our Lactide-Caprolactone Copolymer is manufactured under a quality management system. Each batch is characterized for critical parameters including monomer ratio, molecular weight, polydispersity, and residual monomers to ensure consistency and performance for demanding applications. Certificates of Analysis (COA) with detailed specifications are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 15-25°C. This material is hygroscopic (moisture-sensitive) and should be handled in a dry environment to prevent hydrolysis and molecular weight degradation. Keep away from strong oxidizers.
