Patent ID: 8501838

Claim:
A composite wood board having dimensions of at least 11.8 inches×11.8 inches (30 cm×30 cm) comprising wood particles and an organic binder, wherein the organic binder is substantially formaldehyde free and is selected from the group consisting of: a binder based on a reducing sugar, a binder based on an aldehyde containing sugar, a binder which includes at least one reaction product of a carbohydrate reactant and an amine reactant, a binder which includes at least one reaction product of a reducing sugar and an amine reactant, a binder which includes at least one reaction product of a carbohydrate reactant and a polycarboxylic acid ammonium salt reactant, and a binder which includes at least one reaction product from a Maillard reaction; where the composite wood board has one or more of the following characteristics: a modulus of elasticity (MOE) of at least 1800 N/mm 2 , a bending strength (MOR) of at least 14 N/mm 2 , an internal bond strength (IB) of at least 0.28 N/mm 2 , a thickness swelling after 24 hours in water at 20° C. of less than or equal to 12%, a water absorption after 24 hours in water at 20° C. of less than or equal to 40%.
