Main technical properties and estimated costs of different PPMs.
| Item | Particle Appearance | Meltable Temperature (°C) | Melt Flow Rate (g/10 min) | Estimated Cost * (RMB/ton) |
|---|---|---|---|---|
| PPM0 | White | 180 | 9.94 | 4000 |
| PPM3 | Light yellow | 170 | 125.28 | 4033 |
| PPM3-g-MAH | Light yellow | 150 | 142.75 | 4108 |
| PPM3-g-MAH/5ESO | Light yellow | 150 | 109.82 | 4328 |
Note: * The estimated cost is calculated only up to the cost of the raw materials regardless of processing, energy, and labor costs. The market prices of waste PP, DCP, MAH, and ESO are approximately 4000 RMB/ton, 11,000 RMB/ton, 5000 RMB/ton, and 4400 RMB/ton, respectively, by August 2024 in China.
