Description

Poly(3-Hydroxybutyrate-Co-3-Hydroxyvalerate) (PHBV) is a biodegradable and biocompatible thermoplastic polyester belonging to the polyhydroxyalkanoate (PHA) family. This copolymer is highly valued for its sustainable profile, being derived from renewable resources and offering a viable alternative to conventional petroleum-based plastics. It is essential for manufacturers and R&D teams in the packaging, biomedical, and specialty materials sectors seeking eco-friendly material solutions. The material's properties, such as crystallinity and degradation rate, can be finely tuned by adjusting the 3-hydroxyvalerate (3HV) content.

Application

• Biodegradable Packaging: Used in the production of films, containers, and disposable items that require compostable end-of-life characteristics.
• Medical Devices & Implants: Serves as a material for absorbable sutures, drug delivery matrices, and tissue engineering scaffolds due to its biocompatibility and controlled degradation.
• Agricultural Films: Employed in mulch films and controlled-release systems for fertilizers or pesticides, degrading naturally in soil.
• 3D Printing Filaments: Formulated into specialty filaments for additive manufacturing of prototypes and custom biodegradable parts.
• Consumer Goods: Incorporated into eco-friendly products such as disposable cutlery, cosmetic containers, and toys.
• Coating & Adhesive Formulations: Acts as a biodegradable binder or coating material for paper and cardboard products.

Quality Control

Our Poly(3-Hydroxybutyrate-Co-3-Hydroxyvalerate) is produced under strict quality management systems. Each batch is characterized for critical parameters including copolymer composition, molecular weight, thermal properties, and purity to ensure consistent performance. Certificates of Analysis (COA) detailing specifications and test results are provided with every shipment. We support compliance with relevant standards for biodegradable materials and can tailor specifications to meet specific application requirements.

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); prolonged exposure to high humidity should be avoided to prevent property degradation. Keep away from strong heat sources and open flames.
