    摘要: The extruded propylene-based resin foam according to the present invention is extruded propylene-based resin foam that is formed by extrusion-foaming a propylene-based resin, and the extruded propylene-based resin foam has the expansion ratio of 10 or more and the average cell diameter of less than 400 μm. In addition, the extruded foam contains a 60 or less wt % fibrous filler in relation to the whole molding material. With this configuration, the extruded foam can have a plurality of foam cell walls therein. Thus, the extruded foam can efficiently block external radiant heat, thereby realizing excellent insulation efficiency. Furthermore, because the fibrous filler is oriented along the thickness direction, even when the extruded foam is slightly strained in the thickness direction, a high stress arises, thereby improving energy-absorbing capability.

    摘要: An object of the present invention is to provide an extruded propylene-based resin foam in which a average diameter of cells therein can be reduced while a high expansion ratio remains high, thereby providing an excellent insulation efficiency. The extruded propylene-based resin foam according to the present invention is extruded propylene-based resin foam that is formed by extrusion-foaming a propylene-based resin, and the extruded propylene-based resin foam has the expansion ratio of 10 or more and the average cell diameter of less than 400 μm. With this configuration, the extruded foam can have a plurality of air bubble walls therein. Thus, the extruded propylene-based resin foam can efficiently block external radiant heat, thereby realizing excellent insulation efficiency.

    摘要: The extruded propylene-based resin composite foam (1) according to the present invention is provided by extrusion-foaming a molding material containing a propylene-based resin. The propylene-based resin forming the extruded foam has an olefin-based polymer whose loss tangent (tan δ) is 0.04 to 100 at a temperature of 298 K and a frequency of 10 Hz. The molding material includes a fibrous filler in an amount of more than 0 mass % and 60 mass % or less of the entirety of the molding material. The extruded composite foam (1) includes: first extruded foam (2) whose closed cell content is 40 percent or more and whose expansion ratio is 10 or more; and second extruded foam (3) whose closed cell content is less than 40 percent and whose expansion ratio is 10 or more.
