Description

Poly[(R)-3-Hydroxybutyric Acid-Co-(R)-3-Hydroxyvaleric Acid (~9:1)] is a high-performance, biodegradable biopolymer belonging to the polyhydroxyalkanoate (PHA) family, specifically a copolymer of 3-hydroxybutyrate (3HB) and 3-hydroxyvalerate (3HV). This material offers a unique combination of biodegradability, biocompatibility, and tunable mechanical properties, making it a sustainable alternative to conventional petroleum-based plastics. It is essential for industries seeking eco-friendly material solutions for packaging, medical devices, and specialty films. Our supply ensures consistent quality and reliable material performance for your advanced manufacturing needs.

Application

• Biodegradable Packaging: Used in the production of compostable films, food containers, and shopping bags that degrade in industrial composting facilities.
• Medical & Pharmaceutical Devices: Serves as a biocompatible material for sutures, drug delivery matrices, tissue engineering scaffolds, and other implantable medical devices.
• Agricultural Films: Employed in mulch films and controlled-release matrices for fertilizers or pesticides that biodegrade in soil, reducing plastic waste.
• 3D Printing Filaments: Formulated into specialty filaments for additive manufacturing, offering a sustainable option for prototypes and functional parts.
• Disposable Consumer Products: Used in the manufacture of single-use items like cutlery, cups, and straws designed for commercial composting.
• Coatings & Adhesives: Acts as a base for water-resistant, biodegradable coatings for paper and cardboard or as a component in specialty adhesives.

Quality Control

Our Poly[(R)-3-Hydroxybutyric Acid-Co-(R)-3-Hydroxyvaleric Acid] is produced under strict quality management systems. Each batch undergoes rigorous testing for critical parameters including copolymer composition, molecular weight distribution, thermal properties, and residual monomer content to ensure consistent performance and compliance with relevant material specifications. Certificates of Analysis (COA) detailing all test results 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 a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Prolonged exposure to high humidity or elevated temperatures should be avoided to prevent hydrolysis and maintain polymer integrity.
