Description

Heparinized Hydrophilic Polymer CAS NO 56939-97-0 is a specialized biomaterial created by covalently bonding heparin, a natural anticoagulant, to a hydrophilic polymer backbone. This engineered material is critical for creating non-thrombogenic, blood-compatible surfaces in medical devices. It is essential for manufacturers in the medical technology and pharmaceutical industries seeking to enhance the safety and performance of implantable and extracorporeal devices that contact blood.

Application

• Medical Device Coatings: Applied to catheters, guidewires, stents, and vascular grafts to prevent blood clot formation and reduce platelet adhesion.
• Extracorporeal Circuits: Used to coat blood tubing, oxygenator membranes, and dialysis filters in heart-lung machines and hemodialysis systems to minimize systemic anticoagulation needs.
• Implantable Sensors and Drug Delivery Systems: Enhances biocompatibility and prevents biofouling on surfaces of long-term implants.
• Tissue Engineering Scaffolds: Incorporated into hydrogel or polymer matrices to create pro-angiogenic and hemocompatible environments for regenerative medicine.
• In Vitro Diagnostics (IVD): Used to modify surfaces of microfluidic chips and assay platforms to prevent non-specific protein binding in blood-based tests.
• Research & Development: Serves as a key material for studying heparin-biomaterial interactions, surface hemocompatibility, and controlled drug release.

Quality Control

Our Heparinized Hydrophilic Polymer is manufactured under a quality management system. Each batch undergoes rigorous analytical testing to ensure consistent bioactivity, purity, and performance. Key parameters monitored include heparin content/activity, degree of substitution, and polymer integrity. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). This material is light-sensitive (store away from light). For long-term stability, consider storage under inert atmosphere or refrigeration (2-8°C) as specified for certain grades. Keep away from strong oxidizing agents.
