Polystyrene (PS/GPPS) - Granular

Polystyrene granules are small, pre-processed pellets of polystyrene (PS), a transparent and rigid thermoplastic widely recognized for its ease of shaping and processing. As a versatile raw material, these granules are extensively used in manufacturing methods such as injection molding, extrusion, and thermoforming, enabling mass production across various industries. Key sectors—including packaging, consumer goods, and scientific equipment—utilize polystyrene granules to create both clear and opaque items ranging from disposable petri dishes and protective packaging containers to prototype parts used in research and product testing. Beyond industrial use, polystyrene granules serve as a fundamental model in polymer science for examining thermal behavior, molecular chain entanglement, and the influence of chemical additives on strength and flexibility. Due to their lightweight nature, dimensional stability, and optical transparency, polystyrene granules continue to play a pivotal role in both applied manufacturing and experimental material studies.
