PHB Granules

PHB Granules, composed of polyhydroxybutyrate, are biodegradable and biocompatible thermoplastic materials synthesized by microorganisms. Their crystallinity, biodegradability, and mechanical performance comparable to polypropylene make them highly relevant for biomedical, packaging, and agricultural applications. Industries utilize PHB granules in medical implants, controlled drug delivery devices, and biodegradable films. Research areas include tissue engineering scaffolds, enzyme-mediated surface functionalization, and polymer blending for improved toughness. The granular form allows for easy melt processing, extrusion, and blending with other biodegradable polymers. As an environmentally friendly substitute for petroleum-based plastics, PHB granules are central to innovation in sustainable materials science, combining functional versatility with eco-responsibility.
