The extrusion foaming process involves several critical steps, in which the physical foaming agent plays a significant role: plasticization, solubility, nucleation and bubble growth. PP Physical Foaming Insulation Material is one of the physical foaming agent. Although these aspects can be studied by different techniques, a novel method based on ultrasonic sensors has proven to

1. The mechanical, rheological, morphological and thermal properties of a polypropylene (PP) matrix reinforced with single-walled nanotubes (SWNTs) and poly(propylene-grafted-maleic acid) (PP-g-MA) content were investigated by melt processing. PP-g-MA was used as a Maleic Anhydride Modified PE to promote carbon nanotube dispersion. 2. Compared to uncompatibilized PP/SWNT nanocomposites, the tensile modulus of the material increased

1. The invention discloses a preparation method of polymer supercritical carbon dioxide Foaming Nucleating Agent. The preparation method includes: adding ethanol solution dissolving CO2-hydrophilic substances into porous inorganic nano particles under the condition of 0.1MPa, sufficiently stirring and directly drying to obtain the polymer supercritical carbon dioxide Foaming Nucleating Agent. 2.The CO2-hydrophilic substances are ion
