PS Powder (Polystyrene Powder) is widely used in materials science, microencapsulation, 3D printing, and composite formulation due to its thermal stability, low density, and versatility. It plays a key role in polymer blends, coatings, and dispersion formulations to modify mechanical and surface properties for industrial, electronic, and diagnostic applications. In research laboratories, polystyrene microstructures aid in precision engineering, nanotechnology innovations, and controlled-release formulations. Additionally, PS powder enhances polymer processing in thermoplastic composites, making it valuable for advanced manufacturing, electronic components, and biomedical lab consumables.
