Description

Polycaprolactone-B-Polytetrahydrofuran-& CAS NO 9051-88-1 is a high-performance, biodegradable block copolymer composed of polycaprolactone (PCL) and polytetrahydrofuran (PTHF) segments. This material is engineered to offer a unique balance of elasticity, toughness, and controlled degradation, making it a critical component in advanced material formulations. It is primarily sought after by manufacturers in the biomedical, specialty adhesive, and advanced polymer composite industries for applications requiring tailored mechanical and degradation properties.

Application

• Biomedical Implants & Devices: Used as a key polymer in bioresorbable scaffolds, sutures, and drug delivery matrices due to its biocompatibility and tunable degradation rate.
• Specialty Adhesives & Sealants: Serves as a high-performance elastomeric modifier in formulations requiring flexibility, adhesion, and environmental resistance.
• Advanced Polymer Blends & Composites: Acts as a compatibilizer and toughening agent in polymer alloys to enhance impact strength and processing characteristics.
• Controlled-Release Systems: Employed in agricultural and pharmaceutical sectors for the encapsulation and sustained release of active ingredients.
• 3D Printing Filaments: Utilized in additive manufacturing for producing flexible, durable, and biodegradable prototypes and end-use parts.
• Elastomeric Fibers & Coatings: Provides elasticity and resilience in technical textiles, non-wovens, and protective coatings.

Quality Control

Our Polycaprolactone-B-Polytetrahydrofuran block copolymer is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GPC for molecular weight distribution, NMR for block composition verification, and DSC for thermal property analysis, to ensure consistent performance and purity. Certificates of Analysis (COA) detailing all specifications are available upon request, supporting compliance in regulated applications.

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); keep the original container sealed under an inert atmosphere such as nitrogen to prevent moisture absorption and potential polymer degradation.
