| titleOfInvention | Extruded polypropylene resin foam and method for producing the same |
| abstract | (57) [Summary] [PROBLEMS] To obtain a polyethylene resin extruded foam having a low-density and dense cell surface, periodic unevenness in thickness called corrugation occurs, thereby reducing product value. An object of the present invention is to provide a sheet- or plate-like extruded polypropylene-based resin foam having a low density, having no periodic unevenness in thickness, and having an excellent surface condition. SOLUTION: The extruded polypropylene resin foam of the present invention is a sheet-shaped or plate-shaped extruded polyethylene resin foam, wherein the average thickness of the foam 1 is 1.0 mm or more, and the apparent density of the entire foam 1 is Is 130 g / L or less, and at least one surface side has an average number of bubbles of 30 cells / 9 m on the surface. When the thickness of the foam is measured every 1 cm in a direction perpendicular to the extrusion direction at an arbitrary position along the extrusion direction of the foam while having the surface layer 3 of m 2 or more, a periodic thickness is recognized. If there is no thickness or the thickness is small, the value obtained by dividing the maximum value of the thickness in one cycle of the thickness by the minimum value is 1.15 or less. |
