Light weight
Foam is a material characterized by an internal bubble structure. The large number of bubbles ensures that it is very light in comparison with the original material. SunForce™ is an expanded engineering plastic made primarily from modified polyphenylene ether resin (mPPE) whereas common expanded plastics are made from polystyrene or polyolefin. SunForce™ beads are available in four main densities.
Below is a comparison of the density of SunForce™ with other materials. SunForce™ has lower density than metals or injected resins; therefore, designing components with SunForce™ reduces the weight of your final products.
| Material | Density (g/cc) |
|---|---|
| Iron | 7.87＊1 |
| Aluminum | 2.70＊1 |
| Poly carbonate | 1.20＊2 |
| Polyamide 66 | 1.13 - 1.15＊2 |
| Polystyrene (homopolymer) | 1.04-1.05＊2 |
| Polystyrene (HIPS) | 1.03-1.06＊2 |
| mPPE | 1.04-1.10＊2 |
| SunForce™ 5x | 0.20 |
| SunForce™ 7x | 0.14 |
| SunForce™ 10x | 0.10 |
