Abstract:
The present invention relates to a composite product comprising a thermally modified solid wood component coated with a layer of a composite material which composite material comprises thermally modified cellulosic material and a polymer. The invention also relates to a process for producing said composite product.
Abstract:
The present invention relates to a process for the treatment of solid wood wherein the process comprises the step of: impregnating wood with a solution comprising citric acid and curing the impregnated wood at a temperature of between 150-220°C. The invention further relates to wood treated according to the process.
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 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.
