Description

Castor Oil, Polymer With Glycerol And Sebacic Acid is a biodegradable polyester derived from renewable resources. This polymer is valued for its excellent biocompatibility and controlled degradation profile, making it a cornerstone material for advanced medical and sustainable industrial applications. It is primarily sought by manufacturers in the biomedical, pharmaceutical, and specialty chemical sectors for creating resorbable medical devices, drug delivery systems, and high-performance bioplastics.

Application

• Resorbable Medical Devices: Used as a key material for surgical sutures, bone fixation devices (pins, screws), and tissue engineering scaffolds due to its biocompatibility and predictable degradation rate.
• Controlled Drug Delivery Systems: Employed in the fabrication of microspheres, nanoparticles, and implantable matrices for the sustained and localized release of pharmaceutical actives.
• Biodegradable Polymers & Plastics: Serves as a base polymer for producing environmentally friendly packaging films, coatings, and molded articles designed to degrade under specific conditions.
• Cosmetic & Personal Care Formulations: Incorporated into advanced skincare products as a film-forming agent, encapsulant for active ingredients, or to provide sustained-release benefits.
• Specialty Adhesives and Sealants: Utilized in formulating bio-based adhesives for medical or niche industrial applications where biodegradability is required.
• 3D Printing Filaments: Processed into filaments for additive manufacturing (FDM, SLA) of custom biomedical models and biodegradable prototypes.

Quality Control

Our Castor Oil, Polymer With Glycerol And Sebacic Acid is manufactured under a quality management system. Each batch undergoes rigorous testing for critical parameters including intrinsic viscosity, molecular weight distribution, residual monomer content, and thermal properties to ensure consistent performance and compliance with relevant specifications for biomedical and industrial use. Certificates of Analysis (COA) documenting purity, identity, and key physical characteristics are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen or argon) is recommended to preserve its properties. Keep away from strong oxidizing agents.
