Values of dynamic rheological parameters (G′, G″, and tan δ) of raw and agglomerated PPSPs with different concentrations of MD binder.
| Sample | MD Concentration (%) |
G′ (Pa) | G″ (Pa) | tan δ |
|---|---|---|---|---|
| Raw PPSP | 6.71 ± 0.05 c | 12.1 ± 0.01 c | 1.80 ± 0.02 d | |
| Agglomerated PPSP |
0 (control) | 8.13 ± 0.03 b | 14.3 ± 0.08 b | 1.76 ± 0.00 e |
| 10 | 8.68 ± 0.04 a | 15.8 ± 0.03 a | 1.82 ± 0.01 d | |
| 20 | 5.48 ± 0.03 d | 11.1 ± 0.06 d | 2.02 ± 0.00 c | |
| 30 | 2.27 ± 0.04 e | 6.15 ± 0.04 e | 2.71 ± 0.04 b | |
| 40 | 1.86 ± 0.03 f | 5.70 ± 0.08 f | 3.07 ± 0.03 a |
Each value is the mean of triplicate measurements ± SD. Means with different lowercase letters (a–f) within each column are significantly different (p < 0.05).
