Abstract: In a method of forming a foamed PVC board, a foamed PVC core is formed to have about 1% to about 40% fly ash by weight for adhesion enhancement. Film is laminated to the foamed PVC core with an adhesive between the foamed PVC core and the film. The fly ash in the PVC core enhances the adhesion between the foamed PVC core and the film 120 is increased and resists delamination of the film. A PVC board includes a foamed PVC core, an adhesive, and a film. The foamed PVC core has about 1% to about 40% fly ash by weight for enhanced adhesion between the film and the foamed PVC core. The film is laminated to the foamed PVC core with the adhesive between the foamed PVC core and the film.

Abstract: A siding system that includes a plank of siding made from a first material and a seam plate having a first layer and a second layer. The first layer includes a front face and a back face and is made from the first material. The second layer has a front face connected to the back face of the first layer and is made of a second material.

Abstract: A construction component comprising a foamed cellular board comprising smooth exterior surfaces separated by a cellular network and cut edges, and sealed caps adhered to the cut edges on the foamed cellular boar. The board has a density of less than 0.55 g/cm3, and the cut edges on which the sealed caps are adhered are unmelted edges.

Abstract: A method for making ornamental trim for use in construction comprising applying a sealing composition having PVC particles in a flowable medium to a cut edge of a foam board, heating the sealing composition to a temperature at which the flowable medium solvates the PVC particles, and cooling the sealing composition to form a continuous sealing cap on the cut edge. A construction component consisting essentially of a foamed cellular board comprising smooth exterior surfaces separated by a cellular network and cut edges, and sealed caps adhered to the cut edges on the foamed cellular board comprising PVC in a polymer matrix. The board has a density of no more than 0.5 g/cm3, and the cut edges on which the sealed caps are adhered are unmelted edges.

Abstract: A cross-laminated film comprising at least a two layers and including a thermoplastic component and an elastic component to provide special elastic characteristics for certain packaging and wrapping applications.

Abstract: The present invention generally relates to an extruded thermoplastic board having a light weight relative to its thickness, as well as enhanced mechanical strength relative to its weight. More specifically, the present invention relates to an extruded, thermoplastic board that is corrugated (e.g., a board containing internal ribs), that is both thick and light weight, and that has enhanced mechanical strength. The present invention is additionally directed to a process for preparing such a board.

Abstract: The present invention is an extruded hollow thermoplastic sheeting, which is made of a pair of flat and parallel sheets spaced apart and interconnected by extending ribs of shifted patterns, e.g. of a sigmoid pattern, is disclosed in this invention. The thermoplastic sheeting of the invention has stronger tear strength and balanced physical properties as compared to hollow thermoplastic sheeting with extending ribs of straight pattern of the same specification. The present invention also provides a method for production thereof, wherein a fixing and cooling assembly is oscillated relative to a die, or vice versa, to create the ribs of shifted patterns.

Abstract: An extruded hollow thermoplastic board, which includes a pair of flat and parallel sheets spaced apart and interconnected by extending ribs, generally has a plurality of depression bands in the areas where the flat sheets and extending ribs are joined. The bands, which negatively affect the surface flatness, are especially apparent for crystalline thermoplastic materials. A hollow thermoplastic board, which effectively reduces the depth of the depression bands by inclusion of locationally fixed gas pockets in the rib area during production, is disclosed in the present invention. The hollow thermoplastic board of the present invention substantially enhances the surface smoothness and is highly beneficial to applications such as printing, lamination and graphic art. The present invention also provides a method for production of the hollow thermoplastic boards of smooth surfaces.
