    • A crosslinkable thermal interface material is produced by combining at least one rubber compound, at least one amine resin and at least one thermally conductive filler. This interface material takes on the form of a liquid or “soft gel”. The gel state is brought about through a crosslinking reaction between the at least one rubber compound composition and the at least one amine resin composition. Once the foundation composition that comprises at least one rubber compound, at least one amine resin, and at least one thermally conductive filler has been prepared, the composition must be compared to the needs of the electronic component, vendor, or electronic product to determine if a phase change material and/or at least one solvent is needed to change some of the physical properties of the composition. A method for forming the crosslinkable thermal interface materials disclosed herein comprises a) providing at least one saturated rubber compound, b) providing at least one amine resin, c) crosslinking the at least one saturated rubber compound and the at least one amine resin to form a crosslinked rubber-resin mixture, d) adding at least one thermally conductive filler to the crosslinked rubber-resin mixture, and e) adding a wetting agent to the crosslinked rubber-resin mixture. This method can also further comprise adding at least one phase change material to the crosslinked rubber-resin mixture. The contemplated thermal interface material can be provided as a dispensable liquid paste, a gel, a tape, or a film. Applications of the contemplated thermal interface materials described herein comprise incorporating the materials into a layered material, an electronic component or a finished electronic product.
    • 通过组合至少一种橡胶化合物,至少一种胺树脂和至少一种导热填料来制备可交联热界面材料。 该界面材料采取液体或“软凝胶”的形式。 凝胶状态是通过至少一种橡胶组合物与至少一种胺树脂组合物之间的交联反应引起的。 一旦制备了包含至少一种橡胶化合物,至少一种胺树脂和至少一种导热填料的基础组合物,则该组合物必须与电子部件,供应商或电子产品的需要进行比较,以确定是否 需要相变材料和/或至少一种溶剂来改变组合物的一些物理性能。 形成本文公开的可交联热界面材料的方法包括:a)提供至少一种饱和橡胶化合物,b)提供至少一种胺树脂,c)使至少一种饱和橡胶化合物和至少一种胺树脂交联以形成 交联的橡胶 - 树脂混合物,d)在交联的橡胶 - 树脂混合物中加入至少一种导热填料,和e)在交联的橡胶 - 树脂混合物中加入润湿剂。 该方法还可以进一步包括向交联的橡胶 - 树脂混合物中加入至少一种相变材料。 预期的热界面材料可以作为可分配的液体糊剂,凝胶,胶带或薄膜来提供。 本文所述的预期热界面材料的应用包括将材料结合到分层材料,电子部件或成品电子产品中。

    • Lightweight, non-woven loop products for hook-and-loop fastening are disclosed, as are methods for making them and end products employing them. The products are non-woven webs of entangled fibers of substantial tenacity, the fibers forming both a sheet-form web body and hook-engageable, free-standing loops extending from the web body. The product is stretched and stabilized to produce spaced-apart loop clusters extending from a very thin web of taut fibers. In important cases a binder is added to stabilize the product in its stretched condition. An example of the loop product is produced by needle-punching a batt of staple fibers in multiple needle-punching operations, applying a foamed acrylic binder, and then stretching the needled batt and curing the binder with the batt stretched. Other forming techniques are disclosed and several novel articles and uses employing such loop products are described, such as for filters and fasteners.
    • 公开了用于钩环紧固的轻质无纺布环产品,以及用于制造它们和使用它们的最终产品的方法。 这些产品是具有相当强度的缠结纤维的无纺网,纤维形成片状网状体和从腹板体延伸的可钩接合的独立环。 产品被拉伸和稳定,以产生从非常薄的拉紧纤维网延伸的间隔开的环状团簇。 在重要情况下,加入粘合剂以使产品在拉伸条件下稳定。 循环产品的一个例子是通过在多次针刺操作中针刺短纤维进行针刺,施加泡沫丙烯酸粘合剂,然后拉伸针刺毡并用绷带拉伸固化粘合剂来制备。 公开了其它成形技术,并且描述了使用这种环形产品的几种新型制品和用途,例如用于过滤器和紧固件。
