    摘要: Disclosed are a binary random copolymer of propylene and ethylene, and a film to be formed by sheeting the copolymer. The film has good impact strength, good heat-sealability, high stiffness, good anti-blocking and slipping properties, and high transparency. As having excellent heat-sealability at low-temperature, the copolymer and its film are favorably used as substrate layers of laminated or co-extruded multi-layered films.

    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.
