PS Granules are a polymeric plastic material available in 13 variations of different colors and sizes. Polystyrene is known for its rigidity and high impact strength. It is also an electrical insulator and has low water absorption. Common applications of PS Granules include injection molding of plastic parts and extrusion of plastic foils and foam products. The granular form allows easy feeding into processing equipment to produce final products.
