  • Patent number: 8734609
    Abstract: A process for continuous manufacturing of moisture-curable polyurethane formulations used as sealants and adhesives. The process is characterized by the fact that the reactive components are introduced independently, and without the need for a prepolymer, to a mixer. Solid or liquid raw materials can be either pre-blended or fed directly to the mixer, a twin-screw extruder, which provides the requisite energy to homogenously mix the raw materials and drive the chemical reaction. The process is designed so that the extruder barrel and screw allow variable feed addition and heat exchange down the length of the machine. This allows various operations to be performed at different points in the extruder, including reaction, dispersive mixing, distributive mixing and devolitization.

  • Patent number: 8323450
    Abstract: The invention relates to a method of manufacturing a heat storage material that contains heat storage capsules. The heat storage capsules include a phase change material that absorbs and/or discharges latent heat in response to a change in temperature. The phase change material resides within outer shells of the heat storage capsules. The method involves binding abutting peripheral portions of a plurality of heat storage capsules with a molding binder, so as to form an intermediate granular molded heat storage material. An outer peripheral surface portion of the granular molded heat storage material is coated with a coating binder. The coated granular molded heat storage material is then subjected to a treatment that causes the coating binder of the coating layer to polymerize. The invention also relates to heat storage adsorbent materials, and articles (e.g., canisters) that include such heat storage adsorbent materials.
