HIPS 3630 is a high-impact polystyrene designed specifically for the injection molding industry. This grade is tailored to be mixed with crystal polystyrene and is particularly noted for its high melt flow index, which facilitates fast cycling in injection molding processes. It is available in a clean white color, making it suitable for applications requiring a neat appearance.
 
Key Features
High Melt Flow Index: Allows for faster cycling during injection molding, enhancing productivity and efficiency.
Mixable with Crystal Polystyrene: Offers flexibility in application by allowing dilution with crystal polystyrene for tailored mechanical properties.
White Color: Provides a visually appealing finish without the need for additional coloring processes.
 
Applications
Bathroom Accessories: Ideal for producing durable, aesthetically pleasing bathroom fixtures.
Coat Hangers: Suitable for the manufacture of sturdy, lightweight hangers.
General Injection Molding: Adaptable to various other injection molded products requiring high impact resistance and aesthetic appeal.
 
Typical Properties
Melt Flow Index (200°C/5kg): 15 g/10 min (ASTM D-1238), indicating the material’s excellent flow characteristics under heat.
Styrene Residual Monomer: Less than 500 ppm (CLG LABPSG004), ensuring low residual content for enhanced safety.
Vicat Softening Point: 90°C (ASTM D-1525), the temperature at which the polymer begins to soften.
Rockwell Hardness: Scale/L80 (ISO 2039-2), measuring the surface hardness of the material.
Tensile Stress at Yield: 32 MPa (ISO 527-2), showing the stress level at which the material starts to deform.
Tensile Stress at Break: 25 MPa (ISO 527-2), indicating the maximum stress the material can withstand before breaking.
Elongation at Break: 30% (ISO 527-2), demonstrating the material’s ductility and flexibility under stress.
Tensile Modulus: 2300 MPa (ISO 527-2), reflecting the stiffness of the material.
Izod Impact Strength: 3 KJ/m² (ISO 180/1A), indicating the material's ability to resist impact.
 
Conclusion
HIPS 3630 is engineered for industries requiring high-speed injection molding with excellent impact resistance and aesthetic qualities. Its compatibility with crystal polystyrene and high melt flow index make it a versatile choice for manufacturers focusing on efficiency and product quality, particularly in the production of household and commercial items.
