Material comparison
Polystyrene (PS / HIPS) vs ABS
Polystyrene (usually as high-impact HIPS) is the low-cost, easy-forming option; ABS is tougher, more heat-resistant and better for durable, paintable parts.
Polystyrene (PS / HIPS) vs ABS — side by side
| Polystyrene (PS / HIPS) | ABS | |
|---|---|---|
| Cost | Lower | Higher |
| Impact / durability | Good (HIPS) | Higher |
| Heat resistance | Lower | Higher |
| Finish | Good; easy to print | Excellent; paints/plates |
| Typical use | POS, packaging, liners | Housings, covers, automotive, luggage |
Choose Polystyrene (PS / HIPS) when…
- Cost-sensitive displays, packaging and liners
- Easy forming and printing
Choose ABS when…
- Durable, heat-resistant, paintable parts
- Housings, covers and structural trim
The verdict: Choose polystyrene/HIPS to minimise cost on lighter-duty parts; choose ABS for durability, heat resistance and premium finish.
