    • 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.
    • 提供含有可发泡聚合物材料,纳米石墨和1,1,2,2-四氟乙烷(HFC-134)的聚合物泡沫和聚合物泡沫产品。 优选地,可发泡聚合物材料是烯基芳族聚合物材料。 泡沫不含通常用于制备发泡产品的常规发泡剂。 纳米尺度不是化学或表面改性的,并且优选在聚丙烯酸甲酯共​​聚物(EMA)中复合,聚乙烯甲基丙烯酸甲酯共​​聚物(EMA)既用作纳米尺度的介质和载体。 纳米尺度可以以高达60%的载量的量混合在聚合物中。 此外,nanographite作为成核剂,R值增强剂,红外衰减剂,润滑剂,UV吸收剂和加工助剂。 本发明的泡沫组合物产生具有等于或优于用1-氯-1,1-二氟乙烷(HCFC-142b)生产的常规挤出泡沫的R值的挤出泡沫。 发泡产品希望通过常规挤出方法制成。

    • 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.
    • 提供含有可发泡聚合物材料,至少一种发泡剂,红外衰减剂和聚苯乙烯/聚环氧乙烷共聚物的聚合物泡沫和聚合物泡沫产品。 在示例性实施方案中,发泡剂含有HFC。 用聚环氧乙烷接枝的马来酸酐 - 苯乙烯共聚物增加了聚合物泡沫的泡孔尺寸,抵消甚至抵消了由HFC发泡剂和/或红外衰减剂引起的降低的泡孔尺寸。 此外,接枝聚环氧乙烷的马来酸酐 - 苯乙烯的共聚物通过加工工艺窗口扩大和提高发泡剂在聚合物熔体中的溶解度,对组合物中的发泡剂的加工性具有积极的影响。 因此,存在于本发明组合物中的聚苯乙烯/聚环氧乙烷共聚物用作电池放大器,增塑剂和加工助剂。 还提供了一种形成挤出泡沫产品的方法。
