  • Patent number: 10427389
    Abstract: A resin composition which can suppress the deterioration of performances of a multilayer structure due to moisture absorption regardless that the multilayer structure includes a hygroscopic layer whose performance is deteriorated due to moisture absorption, and a multilayer structure including a layer of the resin composition, are provided. Since the resin composition contains a hydrate-forming alkaline earth metal salt having a specific water absorption property, a multilayer structure comprising a layer of the resin composition can exhibit moisture resistance as a whole of the multilayer structure without affecting the appearance thereof.

  • Publication number: 20150093588
    Abstract: Multi-material, three-dimensional fabrication is improved by the use of a purge wall adjacent to an object to absorb transitional artifacts of material changes. The structure of the purge wall may be selected to reduce build time, and to reduce certain printing artifacts such as warping and delaminating. For example, alternating layers of offset or mirrored zigzag patterns may be used to reduce and distribute the layer-to-layer adhesion surfaces throughout the purge wall while providing sufficient contact points to maintain the structural integrity of the purge wall.

  • Patent number: 8980144
    Abstract: The invention relates to a method for producing a biaxially oriented polypropylene film including at least one layer, which is constructed from propylene polymer B and a propylene polymer that has been recycled once. The method includes heat and melting propylene polymer B in a first extruder and heating a melting a propylene polymer A without a fraction of recycled material in a second extruder. The molten mass of the propylene polymer A is fed to two sides of the propylene polymer molten mass of B such that the propylene polymer A forms border regions of the film during the production process. The two border regions are then cut off after longitudinal and traverse stretching of the film, and melted and mixed together with the propylene polymer B and extruded to form a precursor film in the first extruder. The biaxially oriented polypropylene film comprising a propylene polymer that has been recycled only once is useful for producing capacitors.
