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： Polymeric foam and polymeric foam products that contain a foamable polymer material, at least one blowing agent, an infrared attenuating agent, and a polystyrene/polyethylene oxide copolymer are provided. In exemplary embodiments, the blowing agent contains an HFC. The maleic anhydride-styrene copolymer grafted with polyethylene oxide increases the cell size of the polymer foam and offsets or even negates the decreased cell size caused by an HFC blowing agent and/or infrared attenuating agents. In addition, the copolymer of maleic anhydride-styrene grafted with polyethylene oxide has a positive affect on the processability of the blowing agent(s) in the composition by both widening the process window and enhancing the solubility of the blowing agent in the polymer melt. Thus, the polystyrene/polyethylene oxide copolymer present in the inventive composition acts as a cell enlarger, a plasticizer, and a processing aid. A method of forming an extruded foam product is also provided.

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： 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. The final foamed products may be utilized in building application such as foamed insulation products and in underground applications such as highway insulation. A preferred modifier-free nanoclay is Na+MMT. Modifier-free nanoclay particles may be injected into a polymer during an extrusion foaming process. In another embodiment of the invention, polymer beads containing water/nanoclay particles are formed using inverse emulsion/suspension polymerizations and expanded or extruded into a foamed product. In a further embodiment, a modifier-free nanoclay particle is encapsulated in a super-absorbent material, which may be used in an expanding or extruding process.

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, at least one hydrofluorocarbon (HFC) blowing agent, an infrared attenuating agent such as nanographite, and propylene carbonate, ethylene carbonate, or butylene carbonate as a process additive are provided. In one or more embodiments, the HFC blowing agent is 1,1-difluoroethane (HFC-152a), 1,1,1,2-tetrafluoroethane (HFC-134a), or a combination of 1,1-difluoroethane (HFC-152a) and 1,1,1,2-tetrafluoroethane (HFC-134a). The propylene carbonate, ethylene carbonate, or butylene carbonate acts as a cell enlarger to increase the average cell size of the foamed product, as a process aid, as a plasticizer, and lowers the die pressure. The inventive foam composition produces extruded foams that have insulation values (R-values) that are equal to or better than conventional extruded, closed cell foams produced with 1-chloro-1,1-difluoroethane (HCFC-142b). In exemplary embodiments, less than 4% of the cells are open cells. A method of forming an extruded foam product is also provided.
