Description

Poly(3-Hydroxyoctanoic Acid) is a medium-chain-length polyhydroxyalkanoate (PHA), a class of biodegradable and biocompatible polyesters produced by microorganisms. This material is valued for its unique combination of elastomeric properties, biodegradability, and compatibility with biological systems, making it a sustainable alternative to conventional petrochemical-based polymers. It is primarily sought by industries focused on advanced biomaterials, medical devices, and environmentally friendly packaging solutions. CAS NO 120659-38-3.

Application

• Medical Implants & Devices: Used in the fabrication of biodegradable sutures, tissue engineering scaffolds, and drug delivery matrices due to its biocompatibility and controlled degradation profile.
• Advanced Bioplastics & Packaging: Serves as a key component in producing compostable films, coatings, and molded items for sustainable packaging applications.
• Elastomeric Biomaterials: Utilized in applications requiring flexible, rubber-like materials that degrade in the environment, such as in agricultural films and specialty elastomers.
• Adhesives & Coatings: Acts as a base polymer for bio-based adhesives and functional coatings where biodegradability is a critical requirement.
• Cosmetic & Personal Care: Incorporated into formulations for microbeads or encapsulating agents that are marine and soil biodegradable.
• Research & Development: Employed as a standard or novel polymer in academic and industrial R&D for studying polymer properties, biodegradation pathways, and new material synthesis.

Quality Control

Our Poly(3-Hydroxyoctanoic Acid) is produced under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a suite of analytical techniques including GPC, NMR, and DSC to confirm molecular weight, composition, and thermal properties. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key specifications. Our quality management system adheres to ISO standards, and we can support compliance requirements for research, medical, and industrial applications.

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 hygroscopic (moisture-sensitive); prolonged exposure to high humidity should be avoided to prevent hydrolysis and maintain polymer integrity. Keep away from strong oxidizers and heat sources.
