  • Patent number: 11485832
    Abstract: High-temperature foams are produced and used in the construction of aeroplanes, ships and rail and other vehicles. In particular, the foams are further processed into sandwich materials by joining with two outer layers. To this end, a novel process is used for producing high-temperature foams (HT foams) which are particularly suitable for producing such sandwich components for lightweight construction. This process achieves an improvement in the processability of the HT foams produced and a weight reduction of the sandwich materials. The HT foams are furthermore rigid particle foams which are markedly more economic to produce than rigid block foams. In particular, a reduction is brought about in resin absorption in fibre composite processes through a process-related optimization of the surface constitution.

  • Patent number: 9108171
    Abstract: Provided is a method of manufacturing a resin kneaded product in which an extrusion amount of a material can be increased and by which vent-up at an opening can be suppressed while spouting out of an unmelted material at the opening can be suppressed. A method of manufacturing a resin kneaded product includes kneading a material containing an additive (a) and a thermoplastic resin (b) using a twin screw extruder, in which the twin screw extruder is equipped with a supply port, a discharge port, an opening present between the supply port and the discharge port, a kneading section A present between the supply port and the opening, and a kneading section B present between the opening and the discharge port, a ratio L1 (La/D) of a length La of the kneading section A to a screw diameter D satisfies L1?3, and the material is kneaded in the kneading section A without being completely filled and the material is also kneaded in the kneading section B.

  • Patent number: 9102805
    Abstract: The present invention has its object to provide a masterbatch for foam molding, which can be suitably used for molding processes involving high shearing force, such as kneading molding, calender molding, extrusion molding, and injection molding, which shows a high expansion ratio, and which yields a foamed product with a good appearance. The present invention also has its object to provide a foamed product using the masterbatch for foam molding. A masterbatch for foam molding comprises a base resin and a thermally expandable microcapsule, the base resin being a thermoplastic resin having a melting point of 100° C. or higher, the masterbatch containing 10 to 230 parts by weight of the thermally expandable microcapsule to 100 parts by weight of the base resin, and the masterbatch having a true density of 0.80 g/cm3 or more, a bulk density of 0.35 g/cm3 or more, and a masterbatch size of 450 mg/30 pieces or more.

  • Publication number: 20150130104
    Abstract: A method of fabricating a foamed, injection-molded component is provided. The method includes the step ofplasticizing pellets including a first polymeric material and a second polymeric material within an injection barrel to form an injection material. The first polymeric material defines a first phase of the injection material and the second polymeric material defines a second phase of the injection material. The first and second phases of the injection material are immiscible. The injection material is injected into a mold to fabricate the foamed injection-molded component having microscale, microcellular voids. Upon tensile loading, submicron, secondary phase cavities are formed in the injection-molded component, resulting in improved ductility and toughness.
