General Purpose Polystyrene (GPPS)

General Purpose Polystyrene (GPPS) is a versatile, transparent thermoplastic that is widely used in a variety of applications due to its ease of processing, excellent clarity, and cost-effectiveness. It is produced by the polymerization of styrene monomer and is one of the most commonly used plastics in the world. GPPS is characterized by its rigidity, smooth surface finish, and brittleness, making it ideal for products that require aesthetic appeal, such as clear packaging or decorative items.

Key Specifications:

• Density: 1.04 – 1.06 g/cm³

• Tensile Strength: Moderate

• Melting Point: Approximately 240°C

• Appearance: Transparent, glossy finish

• Packaging: Available in pellet or granule form for industrial use, or custom packaging for bulk deliveries.

Benefits:

• Clarity and Gloss: GPPS has a high degree of transparency and glossy finish, making it ideal for clear packaging and decorative products where appearance is critical.

• Ease of Processing: It is easy to mold, extrude, and form, which makes it suitable for a wide range of manufacturing processes, including injection molding and extrusion.

• Cost-Effective: GPPS is economical compared to other plastics, making it a popular choice for manufacturers looking for a low-cost yet reliable material.

• Brittleness: While it is a strong material, GPPS is brittle, which makes it ideal for products where breakage upon impact is acceptable, such as disposable items.

• Recyclable: Polystyrene is recyclable, which is an important consideration in reducing environmental impact, though it may not be as widely accepted in all recycling programs.

Applications:

• Packaging – GPPS is widely used in food packaging, blister packs, clamshell containers, and disposable cups due to its clarity, low cost, and ease of molding.

• Consumer Goods – Commonly found in toys, cosmetic containers, household goods, and stationery due to its smooth surface and easy decoration.

• Medical – GPPS is used in laboratory ware, syringes, and test tubes because of its clarity, non-toxicity, and cost-effectiveness.

• Electronics – GPPS is used in the production of electronic components, TV screens, and light covers for its electrical insulation properties.

• Advertising and Signage – Its ability to be easily molded into intricate designs makes GPPS suitable for displays, signs, and point-of-sale materials.

Logistics & Trade Terms:

• Loading Ports: Persian Gulf, Southeast Asia, Europe

• Delivery Options: CIF, FOB, or long-term supply contracts

• Certifications: MSDS, COA, SGS inspection, and quality assurance

• Flexible Volume Contracts: Available for both spot and bulk shipments
