High Impact Polystyrene (HIPS) Technical Overview
Material Composition & Characteristics
High Impact Polystyrene (HIPS), supplied by TSH TECH — part of the TSH Group of Companies, is a modified polystyrene resin engineered with an elastomeric component (typically polybutadiene) incorporated during polymerization to enhance impact resistance. This modification imparts a distinctive opaque appearance while maintaining excellent processability across industrial applications.
Key Properties:
Enhanced Impact Strength – Unlike to standard GPPS due to elastomer modification
Good Rigidity – Additionally, it maintains high tensile and flexural strength
Medium Flow Characteristics – As such, it is suitable for various processing methods
Thermal Properties – In terms of heat resistance, it Medium-range heat deflection and Vicat temperatures
Opaque Appearance – Naturally, it is white/off-white, easily colored
Technical Performance:
- Tensile Strength: 25-50 MPa
- Flexural Strength: 40-70 MPa
- Notched Izod Impact: 100-200 J/m
- Heat Deflection Temperature (HDT): 70-90°C @ 1.82 MPa
- Vicat Softening Point: 90-100°C
Processing Methods:
• Injection Molding
• Extrusion
• Thermoforming
• Blow Molding
Common Applications:
- For instance, food packaging containers
- Additionally, refrigerator liners
- Moreover, point-of-purchase displays
- In the medical field, medical device components
- Likewise, consumer electronics housings
- Finally, toys and recreational products
Material Advantages:
- Excellent cost/performance balance-Overall, it provides an excellent balance between affordability and
- Good dimensional stability – Furthermore, it maintains its shape and precision over time.
