摘要： Rigid foam insulating products and processes for making such insulation products are disclosed. The foam products are formed from a polymer, a blowing agent, and nano-graphite. The nano-graphite has a size in at least one dimension less than about 100 nm and, in exemplary embodiments may be an intercalated, expanded nano-graphite. In addition, the nano-graphite may include a plurality of nanosheets having a thickness between about 10 to about 100 nanometers. The nano-graphite acts as a process additive to improve the physical properties of the foam product, such as thermal insulation and compressive strength. In addition, the nano-graphite in the foam controls cell morphology and acts as a nucleating agent in the foaming process. Further, the nano-graphite exhibits overall compound effects on foam properties including improved insulating value (increased R-value) for a given thickness and density and improved ultraviolet (UV) stability.

摘要： Polymer extruded foams that contain cell size enlarging agents are provided. The inventive composition includes a foamable polymer material, at least one blowing agent, and at least one cell size enlarging agent. The blowing agent utilized in the inventive composition is preferably selected such that the composition has a zero ozone depletion and low global warming potential. Examples include any inorganic blowing agents and/or non-hydrogenated chlorofluorocarbons (non-HCFCs). The foamable polymer material is preferably polystyrene. The cell size enlarging agent may be chosen from ethylene vinyl acetate (EVA) and/or ethylene methyl acrylate (EMA). The cell size enlarging agent permits the formation of a foam with large cell sizes that are desirable to achieve a high insulation value and to optimize the physical properties of the foamed product. In addition, the cell size enlarging agent provides an increased cell size to the foamed product without detracting from the physical and thermal properties.

摘要： Polymer extruded or expanded foams that contain modifier-free nanoclays are provided. The addition of modifier-free nano-clays to extruded or expanded foam products improves the thermal properties, mechanical properties, and fire performance properties. Water or a water-containing compound is used as a carrier for the modifier-free nanoclays.

摘要： Provided are methods for producing a high strength, but easily deformed, polystyrene foam board that can endure repeatedly deformations from its original configuration into more complex curved shapes without damaging the board integrity or substantially reducing its structural strength. Also provided are rigid polystyrene foam boards produced by this method that exhibit improved bending and impact resistance while substantially retaining or improving other properties, for example, the thermal dimensional stability and fire resistance, exhibited by corresponding conventional XPS foam boards. The foamable compositions may incorporate one or more of a variety of polymer processing aids for the purpose of altering the performance of the final foam products, thereby allowing the properties of the final foam product to be customized to some degree.

摘要： Polymeric foam and polymeric foam products that contain a foamable polymer material, nanographite, and 1,1,2,2-tetrafluoroethane (HFC-134) are provided. Preferably, the foamable polymer material is an alkenyl aromatic polymer material. The foam is free of other conventional blowing agents typically utilized in preparing a foamed product. The nanographite is not chemically or surface modified and is preferably compounded in a polyethylene methyl acrylate copolymer (EMA), which is used both as a medium and a carrier for the nanographite. The nanographite may be compounded in the polymer in an amount up to 60% loading. In addition, the nanographite acts as a nucleating agent, R-value enhancer, infrared attenuating agent, lubricant, UV absorber, and process aid. The inventive foam composition produces extruded foams that have R-values that are equal to or better than conventional extruded foams produced with 1-chloro-1,1-difluoroethane (HCFC-142b). The foamed products are desirably made by a conventional extrusion process.

摘要： Disclosed is a method for making polystyrene foam which utilizes one or more atmospheric gases, particularly combinations of HFCs and CO2, as the blowing system in combination with a polymer processing aid (PPA), typically an ester that is relatively non-volatile at the extrusion temperature range. The blowing system and the PPA may both be introduced into the molten thermoplastic polystyrene resin or the PPA may be incorporated in the solid source polystyrene resins. The resulting foams will typically exhibit improved dimensional stability at ambient temperatures.

摘要： Polymeric foam and polymeric foam products that contain a foamable polymer material, at least one blowing agent, activated carbon, and water are provided. The activated carbon acts as both a water absorbent and carrier for the water. The activated carbon is able to control and increase cell size even in the presence of carbon dioxide, HFCs, and/or infrared attenuating agents. Additionally, the activated carbon permits a desired amount of water to be introduced into the polymer melt. By controlling the amount of activated carbon and its water content during an extrusion process, a broad range of cell sizes can be obtained in the extruded product. In exemplary embodiments, the activated carbon is added to a primary extruder and water is directly injected into a secondary extruder. Alternatively, the activated carbon is compounded with a polymer resin, pre-hydrated by conditioning or steam impregnation, and added to a primary or secondary extruder.
