    摘要: This invention describes a foamed material wherein the foam is characterized by elongated cells, which have an aspect ratio larger than 1.5, and by a density according to ISO 845 of lower than 150 kg/m 3 , preferably lower than 80 kg/m 3 and a process of manufacturing said material with very good thermal insulation properties. The thermal conductivity is decreased from typical 0.035 W/mK down to 0.025 W/mK by combination of cellular orientation and cell size distribution. In order to be able to achieve necessary cellular orientation level, the melt strength of the polyester resin was significantly increased by reactive extrusion and subsequent foaming, and the extrusion tooling and processing conditions were optimized.

    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.

    摘要翻译: 根据本发明的挤出丙烯类树脂发泡体是通过挤出发泡丙烯类树脂而形成的挤出丙烯类树脂发泡体,挤出的丙烯类树脂发泡体的膨胀比为10以上, 平均泡孔直径小于400μm。 此外,挤出的泡沫相对于整个模塑材料含有60重量%或更少的重量百分比的纤维填料。 通过这种构造,挤出的泡沫体可以在其中具有多个泡沫单元壁。 因此,挤出的泡沫体可以有效地阻挡外部辐射热,从而实现优良的绝缘效率。 此外,由于纤维填料沿着厚度方向取向,所以即使当挤出的泡沫体在厚度方向上稍微应变时,产生高应力,从而提高能量吸收能力。
