Abstract: The claimed invention relates to an improved method for imparting fire-retardancy on wood- and cellulose-based materials that can be employed in the production of furniture and in interior building construction, e.g. wood-based materials and panels, such as lumber (timber) and engineered wood, such as plywood, densified wood, fiberboard (e.g. medium-density fiberboard (MDF) or high-density fiberboard (HDF)), particle board (PB), oriented strand board (OSB), laminated timber, parallel strand lumber (PSL), laminated strand lumber (LSL) and oriented strand lumber (OSL), glued laminated timber (glulam), and laminated veneer lumber (LVL), as well as materials used in decorative interior finishing, such as decorative panels prepared from compact boards (CB) or compact laminates (CL).

Abstract: The current invention concerns a fire retardant composition for use in wood composite panels, either comprising a fire retardant agent or an intumescent formulation, whereby the pH of a 10% aqueous solution of said composition lies between 3.5 and 8.5. The present invention also provides for a specific use of the composition in fire retardant wood composite panels, the respective method for producing those panels, as well as the resulting wood composite panels themselves.

Abstract: The current invention concerns a method for producing an aqueous dispersion suitable for being used as a flame retardant additive to wood composite panels. At least one pH-regulator, at least one inorganic thickener, and optionally at least one smoke suppressing agent is added to a premix while maintaining the actuation of wet-milling systems until the dispersion is obtained.

Abstract: Fire-resistant OSB (oriented strand board) material consisting of a middle layer and two outer layers, wherein the layers primarily consist of bonded wood flakes. There are one or more fire-retardant agents in the middle layer and one or both outer layers, and the nature and/or the concentrations of them in the middle layer are different from the nature and/or the concentrations of them in one or both outer layers.
