Abstract: Disclosed is a high durability cardboard product and a method for the manufacturing thereof. The method includes the steps of applying a cross-linking formulation including at least one cross-linking acid and at least one polyol to a pulp sheet material, pre-drying the pulp sheet material treated with the cross-linking formulation and pre-heating a single sheet or combined multiple sheets of the pre-dried pulp sheet material treated with the cross-linking formulation. At least one cardboard product is shaped and cut out of the pre-heated pulp sheet material, and finally subjected to a final curing step.

Abstract: Disclosed is a method for stabilisation, hydrophobation and enhanced durability treatment of a ligno-cellulosic material. The method includes the steps of applying a cross-linking formulation including at least one cross-linking acid and at least one polyol, and hydophobation emulsion to a ligno-cellulosic material. The chemically treated material is then subjected to a temperature initiating an esterification reaction between the cross-linking acid, the hydroxyl groups of the cellulose and the polyol. Also disclosed is a bio-based material obtainable by the method.

Abstract: The present invention relates to a process for preparing a modified wood product wherein the wood is treated with low-molecular weight resin based on lignin degradation products. The present invention also relates to a modified wood product produced using said process.

Abstract: The present invention relates to a method of making a foamed cellulosic fiber-thermoplastic composite article. The method includes the steps of providing a copolymer composition, combining the copolymer composition and cellulosic fibers, applying heat, mixing energy and pressure to form a foamable mixture, and forming the foamable article in a molding or extruding operation. The method is characterized in that at least 10% of the cellulosic fibers have been thermally modified prior to being combined with the copolymer composition.

Abstract: The present invention relates to an improved process for manufacturing an extruded composite product comprising natural fibers and a thermoplastic polymer. According to the present invention, mixing as well as crosslinking takes place inside an extruder. The natural fibers may be provided for example in the form of pulp or wood particles.

Abstract: The present invention is directed to a composite material comprising a cellulosic material, high impact polystyrene (HIPS) and styrene maleic anhydride (SMA). The cellulosic material may be thermally modified prior to being incorporated into the composite material. The present invention is also directed to a composite product that comprises the composite material according to the invention.

Abstract: The present invention is directed to a method for manufacturing a drylaid mat suitable for thermoforming. The present invention is directed to a dry forming process, wherein cellulosic or lignocellulosic fibers have been impregnated, but not cross linked, with a cross linking agent prior to forming in a dry forming method. The invention is also directed to dry-laid mats manufactured according to the method as well as to thermoformed products manufactured from such dry-laid mats.

Abstract: The invention concerns an extruded composite containing wood fibre material and polymer. The wood fibre material is wood material where the knot or branch content is at least 10 w-%, or bark, or would material into which extract material obtained by extracting knots, branches or bark has been absorbed. The amount of the polymer is 5-25% from the weight of the composite. The composite has high hardness, and reduced moisture absorption and swelling properties. It can be used as constructional material.

Abstract: The present invention relates to a method for applying a wallpaper material onto a surface comprising the steps of providing a liquid suspension comprising cellulosic fibers wherein at least part of said cellulosic fibers comprises microfibrillated cellulose and wherein said liquid suspension has a dry content of at least 10% by weight, applying at least one layer of said liquid suspension onto the surface, drying said liquid suspension layer after it has been applied onto the surface, and thereby forming a dry fiber web layer, wherein said fiber web layer forms said wallpaper material.
