Description

Polycaprolactone Mw 100,000-190,000 is a high molecular weight, biodegradable polyester derived from caprolactone monomers. This specific grade offers an excellent balance of mechanical strength, processability, and controlled degradation, making it a critical material for advanced manufacturing and biomedical research. It is essential for industries requiring robust, biocompatible polymers for long-term implantable devices, specialty adhesives, and high-performance 3D printing filaments.

Application

• Biomedical Implants & Devices: Used as a key polymer for long-term biodegradable scaffolds, bone fixation devices, and drug delivery systems due to its slow degradation profile and biocompatibility.
• Specialty Adhesives & Sealants: Serves as a base resin for high-performance, moisture-curing hot melt adhesives and sealants with excellent flexibility and adhesion.
• Advanced Additive Manufacturing: An ideal feedstock for producing high-strength, flexible, and biodegradable filaments for fused deposition modeling (FDM) 3D printing.
• Tissue Engineering Scaffolds: Fabricated into porous matrices that support cell growth and tissue regeneration, leveraging its tunable degradation rate.
• Controlled-Release Agriculture: Formulated into microcapsules and films for the slow, targeted release of fertilizers, pesticides, and herbicides.
• Polymer Blending & Modification: Employed as a toughening agent or modifier to improve the impact resistance and flexibility of other rigid polymers like PLA or ABS.
• Specialty Coatings: Provides durable, flexible, and biodegradable protective coatings for textiles, paper, and other substrates.
• Modeling Clay & Prototyping: Used in specialty modeling clays and prototyping materials that can be shaped when warm and harden at room temperature.

Quality Control

Our Polycaprolactone is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent molecular weight distribution, purity, and performance characteristics aligned with industry standards for biomedical and specialty polymer applications. Comprehensive Certificates of Analysis (COA) detailing specifications for molecular weight, melting point, residual monomer, and other critical parameters are provided with every shipment.

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). This material is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent moisture absorption, which can affect processing and properties.
