Abstract
A composite includes a first layer of a first fluoropolymer; a second layer of at least one ply of a reinforcing fabric overlying the first layer; and a third layer of a second fluoropolymer overlying the second layer opposite to the first layer, wherein the first layer, the third layer, or combination thereof have an outer surface that is defect free; wherein the composite has a continuous length of at least about 3 meters. Embodiments of such composites can find applications, for example, as processing aids for an electronic device, a food, a polymer, insulating an electrical device, or heat sealing a polymer.
