摘要： A physical barrier having a carrier device and a sealer material applied to the carrier device. The sealer material is configured to expand when it is activated. In its pre-activation state, the sealer material is flowable. The sealer material is applied directly to the carrier in its pre-activation state through a dispensing orifice without being previously molded.

摘要： A baffle may conform to and be magnetically coupled to a body having a ferromagnetic component in proximity to the baffle. The baffle includes a first layer of a flexible thermally expansible baffle material which expands when subjected to an elevated temperature, and a second layer of a flexible magnetic material. The baffle may thereby be flexed to conform to an irregular or curved surface. In addition, the baffle may be preformed to provide an irregular or arcuate portion to conform to the body on which it is placed. The magnetic attachment facilitates attachment and removal without the need to provide holes in the body, and upon heating and expansion of the baffle, the baffle material expands to fill cavities and adhere to the inside wall surface of the body on which it is received.

摘要： An expandable baffle for sealing a cavity of an automobile is provided. The baffle includes a thermally expandable sealing material which has an expansion temperature similar to the temperatures achieved in specific stages of the automotive manufacturing processes (e.g., the paint bake stage). The inventive baffle further includes a support for the sealing material which maintains the material at the desired location within the cavity until thermal expansion. The support is formed of a material having a melting point higher than the thermal expansion temperature of the sealing material. In one embodiment, the support comprises a pair of solid, spaced-apart sidewalls that “bow” upon expansion of the sealing material. In an alternate embodiment, the sidewalls include a plurality of openings formed therein through which the sealing material flows during thermal expansion. The inventive baffles are useful for providing noise attenuation and for sealing the cavity from moisture and contaminants while providing a limited degree of structural reinforcement.

摘要翻译： 提供一种用于密封汽车空腔的可膨胀挡板。 挡板包括热膨胀密封材料，该密封材料的膨胀温度类似于在汽车制造过程的特定阶段达到的温度（例如，油漆烘烤阶段）。 本发明的挡板还包括用于密封材料的支撑件，其将材料保持在腔体内的期望位置，直到热膨胀。 支撑体由熔点高于密封材料的热膨胀温度的材料形成。 在一个实施例中，支撑件包括一对固定的间隔开的侧壁，其在密封材料膨胀时“弯曲”。 在替代实施例中，侧壁包括形成在其中的多个开口，密封材料通过该开口在热膨胀期间流动。 本发明的挡板可用于提供噪声衰减并且用于将空腔与湿气和污染物密封在一起，同时提供有限程度的结构增强。
