Description

Poly(3-Hydroxyvalerate) is a biodegradable, biocompatible polymer belonging to the polyhydroxyalkanoate (PHA) family. This material is valued for its excellent mechanical properties, processability, and its sustainable origin from renewable resources. It is a critical component for manufacturers in the bioplastics, medical device, and specialty packaging sectors seeking high-performance, eco-friendly alternatives to conventional petrochemical-based plastics.

Application

• Biodegradable Plastics & Packaging: Used in the production of compostable films, containers, and disposable items where environmental sustainability is a key requirement.
• Medical & Pharmaceutical Devices: Suitable for absorbable sutures, drug delivery matrices, and tissue engineering scaffolds due to its biocompatibility and controlled degradation profile.
• Specialty Coatings & Adhesives: Acts as a base polymer for bio-based coatings and adhesives, offering good barrier properties and adhesion.
• 3D Printing Filaments: Serves as a raw material for producing filaments used in additive manufacturing for prototyping and custom parts.
• Agricultural Mulch Films: Employed in the formulation of biodegradable mulch films that decompose in soil, reducing plastic waste.
• Consumer Goods: Found in durable yet compostable products such as cutlery, cosmetic containers, and toys.

Quality Control

Our Poly(3-Hydroxyvalerate) is produced under a stringent quality management system. Each batch is characterized for key parameters including molecular weight distribution, thermal properties, and purity to ensure consistent performance. Certificates of Analysis (COA) detailing specifications such as monomer content, residual solvent, and biodegradability are available upon request.

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) and should be kept under dry conditions to prevent hydrolysis and maintain polymer integrity.
