Summary: | A polymer interlayer having improved acoustic characteristics. The polymeric interlayer includes a first polymeric layer, a second polymeric layer, and a third polymeric layer. The first polymer layer is between the second polymer layer and the third polymer layer. The first polymer layer is formed from a resin containing polyvinyl acetate (PVAc). The first polymer layer has a Tg of less than about 20 DEG C and a peak tan delta of greater than about 2.0.
一种具有改进声学特性的聚合物夹层。该聚合物夹层包括第一聚合物层、第二聚合物层和第三聚合物层。第一聚合物层位于第二聚合物层和第三聚合物层之间。第一聚合物层由包含聚乙酸乙烯酯(PVAc)的树脂形成。第一聚合物层具有小于约20℃的Tg和大于约2.0的峰tanδ。 |
