An engineering or constructional member comprising at least two strips bonded with an adhesive; each of the strips comprises bamboo impregnated or treated with a polymer derived from one or more furfuryl alcohol resin precursors.

Decking comprises: a support selected from the group consisting of: polymeric materials; marine engineering polymers, fiber reinforced polymers, polymer metal composites, metal or wood sheets or marine superstructure; an array of strips of polymer treated wood secured to the support by means of an adhesive; the adhesive being selected from the group consisting of: polyurethane adhesives, modified silyl polymer adhesives and epoxy resin adhesives; wherein the polymer treated wood comprises a wood species selected from the group consisting of: maple species impregnated with a wood compatible polymerizable monomer, preferably selected from furfuryl alcohol, bis hydroxymethyl furan and mixtures thereof and subsequently dried and cured.

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.

The present disclosure describes a treated cellulosic material comprising a cellulosic material having a porous structure defining a plurality of pores, at least a portion of the pores containing a treating agent comprising a polymer comprising an ol-efin-carboxylic acid copolymer; and a modifying agent comprising an epoxy.

A process for the manufacture of hydrophobic paper using a pulp comprising a slurry of cellulosic fibers in an aqueous medium comprising an alkoxysilane. A paper or cardboard packaging product comprising cellulosic fibers having a silane residue substantially uniformly distributed throughout the paper or cardboard and bonded to the cellulosic fibers predominantly through SiO bonds.

A novel and inventive method of Wood Modification is provided, combining two singular modification strategies for accessible OH group reduction into one, simultaneous hybrid process, by taking advantage of a high-pressure modification process.

A method of treating a cellulose-based material, for example wood and engineered wood is provided, wherein the process involves the following steps: selecting and placing the cellulose-based material in a treatment chamber; impregnating the cellulose-based material with an impregnating agent consisting of an aqueous solution comprising a fluid suitable for esterification; facilitating a hydrolysis process whereby the impregnating agent reacts resulting in the formation of esters and polyesters inside the cellulosed-based material.
