    摘要: Expandable polymer compositions are used to reinforce or provide various types of insulation to cavities in structural elements. The polymer compositions include at least two different segments, which may or may not be joined. At least one of the segments will expand before another segment when heated. The first-to-expand segment forms a physical barrier to the expansion of later-expanding segments, thereby restricting the expansion of the later-expanding segment in at least one direction. In this manner, the location of the expanded polymer within the cavity can be easily and inexpensively controlled.

    摘要: There is disclosed a closure panel. The panel finds particular utility as a liftgate or endgate for automotive vehicles. Typically, the assembly includes a first panel portion opposite a second panel portion and an intermediate material therebetween. Preferably, one or more of the panel portions is formed of a polymeric material and the intermediate material is preferably a structural foam that can bond to both the first and the second panel portions.
