Formosa Plastics HIPS HP8250: High-Impact Polystyrene Resin
Formosa Plastics HP8250 is a high-quality High-Impact Polystyrene (HIPS) resin, manufactured by Formosa Plastics Corporation (FPC). This opaque thermoplastic is specifically engineered to provide an optimal balance of toughness, rigidity, and excellent processability. It is created by incorporating a rubber component (typically polybutadiene) into the polystyrene matrix, which dramatically increases its impact strength compared to general-purpose polystyrene (GPPS). HP8250 is a versatile and economical material, widely used for its robust performance and ease of molding.
This grade’s excellent flow properties allow for efficient processing in both injection molding and extrusion, making it ideal for creating durable components with a high-quality finish.
Key Features & Benefits
- Superior Impact Resistance: Provides excellent toughness and durability, making it ideal for products that may be subject to accidental drops or impacts.
- Excellent Processability: Its balanced flow properties ensure a wide processing window, allowing for easy molding of complex parts and high productivity.
- Good Rigidity & Stiffness: Maintains sufficient structural integrity for functional components.
- Dimensional Stability: Exhibits low shrinkage and good dimensional consistency, ensuring part precision.
- Versatile Finishability: The material’s surface is excellent for painting, printing, or lamination, offering broad design flexibility.
- Cost-Effective: Provides a low-cost solution for applications where a balance of toughness and rigidity is required.
Typical Applications
Due to its combination of high impact resistance, rigidity, and easy processability, Formosa Plastics HP8250 is widely used across various sectors:
- Appliances: Refrigerator inner linings, parts for air conditioners, and other appliance components.
- Electronics: Housings for computers, printers, TVs, and other electronic devices.
- Consumer Goods: Toys, household items, and durable packaging.
- Food Packaging: Thermoformed food trays and single-use containers.
- Automotive: Interior trims, dashboard components, and other non-critical parts.
Typical Properties (Representative Values)
Please note that specific values may vary slightly depending on the exact production batch and testing conditions. Always refer to the official Technical Data Sheet (TDS) from Formosa Plastics Corporation for the most accurate and up-to-date information.
Processing Guidelines (General Injection Molding)
- Drying: Not typically required for HIPS, but proper storage to prevent moisture absorption is recommended.
- Melt Temperature: 180 – 220 °C.
- Mold Temperature: 30 – 60 °C.
- Injection Speed: A medium to high injection speed is recommended to ensure good mold filling.
Packaging & Storage
Formosa Plastics HP8250 is typically supplied in 25 kg bags or bulk containers. For optimal product quality, store in a dry, cool, and well-ventilated area, away from direct sunlight and heat sources. Keep packaging sealed until ready for use.
