“IMPROVEMENT INTRODUCED IN THE PROCESS OF OBTAINING THERMO-STRUCTURAL COMPOSITES”, resulting from the union of various synthetic materials (F), which go through a phase of couplings (union of materials), to be subsequently heated and pressed into molds (M) of specific size for each part to be molded, at temperatures and pressure suitable for the fusion of these elements, featured by the fact that the thereto-structural composite (1) is obtained from the formation of the substrate (S), with the synthetic fiber molding (F), foams, etc., preferably Non-Woven (NW-TNT)+PE Film+Fiberglass+Semi-Rigid PU Foam embedded in a chemical formulation (FO) of Diphenylmethane Diisocyanate (MDI) in a ratio of 30% to 80% and Methylene Chloride (CM) in the ratio of 20% to 70%; and for processing the product, a catalyst prepared from Dabco Cristal in the ratio of 1% to 30% is used; by adding 70% to 99% water, said substrate (S) may, during the hot-molding phase, receive the addition of finishes (5) and, after the molding phase, receive the addition of minor and complementary structural elements (6).

A house wrap for a building comprises a reinforcing drainage plane layer configured to face the outside of the building; a breathable, non-perforated barrier film bonded to the drainage plane layer; and at least one insulating layer including a perforated expanded low density polyethylene foam layer, wherein in the expanded low density polyethylene layer at least 80% of the blowing agents are dissipated from closed cells within the expanded low density polyethylene layer, forming evacuated closed cells whereby a partial vacuum is formed within the closed cells of the low density polyethylene layer.

Described herein are physically crosslinked, closed cell continuous multilayer foam structures that includes a foam layer comprising polypropylene, polyethylene, or a combination of polypropylene and polyethylene and a polyamide cap layer. The multilayer foam structure can be obtained by coextruding a multilayer structure comprising at least one foam composition layer and at least one cap composition layer, irradiating the coextruded structure with ionizing radiation, and continuously foaming the irradiated structure.

A mat and a method for manufacturing the same are provided. The mat includes a first foam layer, a second foam layer and a third foam layer. The first foam layer has a first hardness and a first porosity. The second foam layer is connected with the first foam layer and has a second hardness and a second porosity larger than the first porosity. The third foam layer is connected with the second foam layer and has a third hardness and a third porosity smaller than the first porosity. The second foam layer includes a first connecting surface facing the first foam layer and a second connecting surface facing the third foam layer. The contact area between the first connecting surface and the first foam layer is different from the contact area between the second connecting surface and the third foam layer.

A polymeric structure includes a first polymeric component and a second polymeric component, the first polymeric component including a first mating surface and an opposing first free surface and the second polymeric component including a second mating surface and an opposing second free surface. The first polymeric component and the second polymeric component are positioned with the first mating surface facing the second mating surface. A charge of molten polymer is disposed between the first mating surface and the second mating surface. A compressive force is applied to the first free surface of the first polymeric component and to the second free surface of the second polymeric component in order to secure the first polymeric component to the second polymeric component in order to form the polymeric structure. The polymeric structure may be a construction mat.
