<p>Provided is a paper structure comprised of two outside layers and at least one inside layer. The two outside layers are comprised of substantially cellulosic pulp fiber, and the inside layer is comprised of a high temperature fiber and a polymeric binder, and preferably cellulosic pulp fiber. In a preferred embodiment, the structure comprises at least three inside layers, all comprised of cellulosic pulp fiber, high temperature fiber and a polymeric binder. The resulting paper structure finds particular use as a high temperature transformer paper in the manufacture of transformers.</p> |
