    • A method of manufacturing a foam body having an anisotropic cell structure, the method including the steps of: expanding a polymer at an elevated temperature to form an initial foam body; and cooling the initial foam body under a negative pressure. There is also provided a method of manufacturing a foam body having an anisotropic cell structure, the method including the steps of: (a) in a first expansion step, expanding a foamable polymer composition substantially isotropically to form an initial foam body having an isotropic cell structure; and (b) in a second expansion step, expanding the initial foam body anisotropically in a selected direction under a negative pressure which applies an expanding force in the selected direction to provide a final foam body having an anisotropic cell structure. Apparatus for the methods are also disclosed.
    • 一种制造具有各向异性单元结构的泡沫体的方法,所述方法包括以下步骤:在高温下膨胀聚合物以形成初始泡沫体; 并在负压下冷却初始泡沫体。 还提供了一种制造具有各向异性单元结构的泡沫体的方法,该方法包括以下步骤:(a)在第一膨胀步骤中,基本上各向同性膨胀可发泡聚合物组合物以形成具有各向同性电池的初始泡沫体 结构体; 和(b)在第二膨胀步骤中,在施加沿所选方向的膨胀力的负压下沿选定方向各向异性膨胀初始泡沫体,以提供具有各向异性单元结构的最终泡沫体。 还公开了用于该方法的装置。
