HIPS WT1235 is designed for the injection molding industry and is typically diluted with crystal polystyrene. This grade is available in a clean white color, making it ideal for applications that require a neat and consistent appearance without additional finishing processes.
 
Key Features
High Impact Resistance: Ensures durability and resistance to physical stresses, making it suitable for products that must withstand mechanical stress.
Good Processability: The ability to be mixed with crystal polystyrene allows for flexibility in processing and application.
White Color: Provides a visually appealing finish, reducing the need for post-processing painting or coating.
 
Applications
Toys: Perfect for manufacturing robust and safe children's toys.
TV Cabinets: Ideal for consumer electronics housings that require a high-quality finish and impact resistance.
Clocks: Suitable for the casings of clocks where aesthetics and durability are essential.
 
Processing Guidelines
Drying: Recommended drying in a desiccant dehumidifying hopper dryer at 180°-190°F (82°-88°C) for 2 hours to achieve a moisture content of 0.1%. Alternatively, drying at 160°-170°F (71°-77°C) for 4 hours is also effective.
 
Typical Properties
Melt Flow Index (200°C/5kg): 5 g/10 min (ASTM D-1238), indicating the material’s flow characteristics during processing.
Styrene Residual Monomer: Less than 500 ppm (CLG LABPSG004), ensuring low residual content for safety.
Vicat Softening Point: 96°C (ASTM D-1525), the temperature at which the polymer begins to soften under a specified load.
Rockwell Hardness: Scale/L70 (ASTM D-785), measuring the surface hardness of the material.
Tensile Stress at Yield: 33 MPa (ASTM D-638), indicating the stress level at which the material starts to deform.
Tensile Stress at Break: 35 MPa (ASTM D-638), showing the material's maximum stress capacity before breaking.
Elongation at Break: 30% (ASTM D-638), demonstrating the material’s ductility and flexibility under stress.
Tensile Modulus: 2980 MPa (ASTM D-638), reflecting the stiffness of the material.
Izod Impact Strength: 3 KJ/m² (ISO 180), indicating the material's ability to resist impact at room temperature.
 
Conclusion
HIPS WT1235 is engineered for manufacturers looking for a high-performance material with excellent impact resistance and aesthetic appeal. Its versatility makes it suitable for a wide range of applications, particularly in the production of toys, TV cabinets, and clock casings, where durability and visual quality are critical.
