Therefore, we chose a temperature node of 180 °C to test HPGA1 and HPGA2. As depicted in Figure 1 c, the oil absorption rate of HPGA1 exhibited a stable trend at 90 s, whereas HPGA2 continued to display an increasing trend under high-temperature conditions before eventually stabilizing at a rate of 4.55 g/g.
