Description

Polycaprolactone (CAS NO 24980-41-4) is a biodegradable, semi-crystalline polyester with excellent biocompatibility and a low melting point. This versatile polymer is highly valued for its ease of processing and tunable degradation profile, making it a critical material in advanced manufacturing. It is essential for industries focused on sustainable materials, medical technology, and specialty additives, where performance and environmental impact are key considerations.

Application

• Biomedical Implants & Devices: Used as a base material for resorbable sutures, drug delivery microspheres, tissue engineering scaffolds, and bone fixation devices due to its biocompatibility and controlled degradation.
• 3D Printing (FDM/FFF): Serves as a low-warpage, easy-to-print filament for prototyping and creating flexible, durable models with a smooth finish.
• Polyurethane Synthesis: Acts as a soft segment precursor in the production of high-performance, biodegradable polyurethane elastomers for coatings, adhesives, and foams.
• Adhesives & Sealants: Functions as a thermoplastic modifier to enhance flexibility, adhesion, and biodegradability in hot-melt and reactive adhesive formulations.
• Controlled-Release Agriculture: Employed in the encapsulation of pesticides, herbicides, and fertilizers to enable slow, targeted release and reduce environmental runoff.
• Modeling & Molding: Ideal for educational, architectural, and hobbyist modeling clay due to its low melting point and reusable properties.
• Polymer Blending & Modification: Used as a compatibilizer or additive to improve the toughness, flexibility, and biodegradability of other polymers like PLA or starch-based plastics.
• Specialty Coatings: Provides a degradable, protective layer for temporary coatings in horticultural or marine applications.

Quality Control

Our Polycaprolactone is produced under a strict quality management system. Each batch undergoes rigorous testing for key parameters including molecular weight distribution, melting point, residual monomer content, and intrinsic viscosity to ensure consistency and performance. Certificates of Analysis (COA) detailing these specifications are available for every shipment. We can supply grades suitable for industrial, technical, and research applications, with tailored specifications available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Although not highly hygroscopic, prolonged exposure to high humidity should be avoided to prevent potential moisture absorption. Keep away from strong oxidizers and heat sources.
