Effects of Posttreatments on the Storage Stability of Reclaimed Rubber

Figure 6

The variation of the crosslink density of the reclaimed rubber samples with storage time. The crosslink density increased with increasing storage days, and due to the higher effectiveness of the two-roll milling process in breaking down the crosslinks, the #1 reclaimed rubber sample had a lower crosslink density than the other two samples, passing through an extruder (#2) and rubber strainer (#3).
