“…With the introduction of an annealing or crystallizing stage, the pressurized vessel loaded with the sample was operated as the following procedures in this study: stage 1, 200°C, 10 MPa, 20 min; stage 2, 110°C, 10 MPa, t a (203,040 min); stage 3, T f (158, 160, 162, 164°C), P f (810,121,416 MPa), t f (203,040 min). 17,49…”

“…To obtain the microcellular iPP‐SEBS foams, a batch foaming process was adopted, using an autoclave with a volume of 25 ml, and the self‐designed temperature controlling system, as well as the three stages processing design, as indicated in our former studies 3,10,27 . The superior advantage of batch foaming method is that it can be selectively set the single foaming parameters such as the saturated temperature, pressure and time.…”

“…Many researchers had strived to find different methods to overcome the melt strength defect of iPP during its foaming process. Of which, different additives had been applied to change its crystallization behavior, and thus to adjust its melt strength, heterogeneous cell nucleating, and foaming abilities 4,9–13 . Nanosized fillers such as nanoclay, nanofibers, carbon nanotubes, and so on were the mostly used additives includes 6,8,13–23 .…”

“…5,6 Moreover, the introduction of NA could also extend the foaming temperature range of PP. For instance, Zhang et al 7 reported that with the combination of a 0.2 wt% α-NA, Bis (3, 4-dimethylbenzylidene) sorbitol (DMDBS) and annealing treatment, microcellular PP foams with cell density over 10 12 cells/cm 3 was obtained and the foaming temperature range increased from only 4 to 63 C for PP.…”
