Polystyrene (PS) is an amorphous thermoplastic known for its rigidity, hardness, and easy processability. Due to its low cost and moldability, PS is one of the most widely used plastics, especially in packaging, household items, and disposable products.Polystyrene (PS) is an amorphous thermoplastic known for its rigidity, hardness, and easy processability.

• Packaging: Trays, cups, lids, inserts, and EPS foam for cushioning.
• Disposable items: Cutlery, plates, and other one
• use goods.
• Household goods: Budget device housings, boxes, containers, and decorative parts.
• Toys: Low
• impact components.
• Construction (EPS/XPS): Thermal and acoustic insulation, lightweight elements, and impact protection.
• Good rigidity and hardness: Enables precise molding and smooth surface finishes.
• Transparency: GPPS (General Purpose PS) offers excellent clarity for displays and packaging.
• Easy processing: Suitable for injection molding, extrusion, and thermoforming.
• Lightweight: Reduces transport costs and simplifies handling.
• Low cost: One of the most economical plastics for mass production.
• Brittleness: Fragile, especially at low temperatures, with low impact resistance.
• Poor chemical resistance: Sensitive to solvents like acetone, benzene, and oils.
• Low heat resistance: Softens at 90–100 °C.
• Poor UV resistance: Yellows and degrades in sunlight without protection.
