    摘要: An impact resistant membrane and methods of preparing and utilizing the membrane are disclosed. The membrane comprises a loft layer, a first polymeric layer bonded to a first surface of the loft layer, and a second polymeric layer bonded to a second surface of the loft layer. The membrane can be fabricated by providing a loft layer and applying a polymeric layer on a first surface and on a second surface of the loft layer. The membrane has a higher resistance to failure due to impact and thus protects the underlying structure membrane for a longer time. A method of facilitating protecting a structure comprises providing a single ply membrane having a loft layer and a polymeric layer disposed on at least two surfaces of the loft layer.

    摘要: A system, in certain embodiments, includes a fluid filter that includes a first set of strips of a first filter material having a first density, and a second set of strips of a second filter material having a second density greater than the first density, wherein the first set and second set of strips are arranged in an alternating pattern to define a first filter layer. The system also includes a second filter layer comprising a third filter material having a third density greater than the second density, wherein the first filter layer is coupled to the second filter layer. In other embodiments, the system includes a fluid filter which includes a first filter material having a first density, a second filter material having a second density greater than the first density, and a third filter material having a third density greater than the second density. The system may also include the first filter material coupled to both the second filter material and the third filter material, as well as the second filter material coupled to both the first filter material and the third filter material.

    摘要: A roofing underlayment having a slip-resistant surface includes a woven polypropylene scrim laminated to a top layer made from a non-woven spun-bond polypropylene fabric. During lamination, the scrim is bonded to the top layer by a polypropylene coating that impregnates the scrim, thereby forming a structural bottom layer comprising the polypropylene-impregnated scrim. The non-woven fibers of the top layer provide a micro-textured, slip-resistant surface. A second polypropylene coating may be applied to the bottom surface of the bottom structural layer. An adhesive layer may optionally be applied either to the bottom surface of the bottom structural layer, or, if used, to the bottom surface of the second polypropylene coating.
