Density: Polystyrene with a density of 1.05 g/cm³ is used in rigid packaging containers, where high structural integrity and lightweight properties are required for efficient storage and transport. Thermal conductivity: Polystyrene with low thermal conductivity (0.033 W/m·K) is used in insulation boards for building construction, where it provides superior thermal insulation and energy efficiency. Molecular weight: Polystyrene with a molecular weight of 200,000 g/mol is used in injection molding applications, where it enables smooth processing and consistent part quality. Purity: Polystyrene with 99.9% purity is used in medical laboratory equipment, where contamination-free performance and safety are essential. Glass transition temperature: Polystyrene with a glass transition temperature of 100°C is used in food service trays, where thermal stability and resistance to deformation at serving temperatures are necessary. Particle size: Polystyrene beads with 0.2 mm particle size are used in expandable foam applications, where controlled bead expansion ensures uniform foam cell structure. Clarity: Polystyrene with high optical clarity is used in CD cases, where crystal-clear visibility and product display are critical. Impact strength: Polystyrene with enhanced impact strength (Izod > 30 J/m) is used for appliance housings, where improved durability and crack resistance under mechanical stress are imperative. Flame retardancy: Polystyrene with UL94 HB flame retardancy is used in electronics packaging, where reduced flammability enhances product safety. Solvent resistance: Polystyrene with high solvent resistance is used in chemical storage vials, where chemical compatibility and long-term containment are required. |
| Packing | Polystyrene is typically packaged in 25 kg multi-layer paper or plastic bags, clearly labeled with product name, manufacturer, and safety information. |
| Container Loading (20′ FCL) | 20′ FCL container loading for polystyrene typically fits 16-20 metric tons, packed in 25kg bags or jumbo bags for export. |
| Shipping | Polystyrene is shipped as solid pellets or beads in sealed, moisture-resistant bags or drums. It is non-hazardous, lightweight, and should be stored away from heat or open flames. Transport containers must be kept dry and protected from mechanical damage to maintain quality and prevent contamination during shipping. |
| Storage | Polystyrene should be stored in a cool, dry, and well-ventilated area away from heat sources, open flames, and direct sunlight, as it is flammable. Keep it in tightly closed containers to avoid contamination. Store away from strong oxidizing agents and solvents. Ensure proper labeling and provide secondary containment to prevent environmental release in case of spills. |
| Shelf Life | Polystyrene typically has an indefinite shelf life if stored in cool, dry conditions away from direct sunlight and chemical contaminants. |
