An efficient pre-foamed method to fabricate low density poly(ether-block-amide) foams
Poly (ether-block-amide) PEBA foams have been widely used in many industrial fields.However, compared with amorphous polymers, the microcellular foaming process of PEBA is more complicated due to their complex phase morphology evolution behavior.Moreover, the productivity was limited owing to the long saturation time for thick samples.In this study
