Especially the combination of higher density and higher thermal conductivity. can make the use of magnetite attractive for the compounder. This is demonstrated in the table below:
| Mass | Mass | V% | V% | |
|---|---|---|---|---|
| PP | Filter | PP | Filter | |
| Barytes | 35 | 65 | 72.4 | 27.6 |
| Magnetite | 35 | 65 | 72.4 | 27.6 |
Taking the Barytes compound (65% filled) as reference, we find that using magnetite at the same volume percentage we can achieve a 15% higher compound density.
Since we are comparing the same filler-volume we can expect similar processing viscosity, however due to the higher conductivity of the magnetite we can expect faster cooling of the moulded/extruded products.
- Our magnetite has magnetic properties which can make the plastic detectable (relevant for food packaging and -processing)
