PS (GPPS, HIPS, EPS)

28Edge supplies a full range of Polystyrene (PS) resins, including General Purpose Polystyrene (GPPS), High Impact Polystyrene (HIPS), and Expandable Polystyrene (EPS). Sourced from leading petrochemical producers in the Middle East and Asia, our PS materials are engineered for clarity, strength, and ease of processing, serving diverse industries such as packaging, consumer goods, insulation, and electronics. 28Edge offers dependable supply under FOB, CIF, and CFR terms, with SGS-certified quality and comprehensive technical documentation.

General Purpose Polystyrene (GPPS) is a transparent, rigid polymer used in food packaging, disposable cups, cosmetic containers, and lighting applications where clarity and dimensional stability are essential. High Impact Polystyrene (HIPS), modified with rubber for toughness, provides superior impact resistance and heat stability, making it suitable for appliance housings, refrigerator liners, and electronic enclosures. Expandable Polystyrene (EPS) is a lightweight, closed-cell foam used in thermal insulation panels, protective packaging, and construction materials due to its excellent cushioning and insulation properties.

28Edge’s PS grades conform to ASTM D1238, D638, and ISO 527 standards, with key specifications including melt flow index, tensile strength, notched Izod impact, and density. Each batch is tested and certified by SGS or Bureau Veritas, ensuring consistency and reliability. Packaging is available in 25 kg bags or bulk containers, accompanied by full Technical Data Sheets (TDS) and Certificates of Analysis (COA).

With its versatility, cost-effectiveness, and recyclability, polystyrene remains one of the most essential thermoplastics for modern manufacturing. 28Edge provides clients with high-purity GPPS, HIPS, and EPS resins, supporting industries that demand precision, efficiency, and sustainable material performance.
