Furfurylated wood

Type of modified wood that is treated with furfuryl alcohol

Furfurylated wood is the end product of treating wood with furfuryl alcohol. This chemical process is also called furfurylation. Furfurylation is a commercially used wood modification process to enhance the physical, mechanical and biological properties of wood. In this process -which is based on principles of wood science- the cell walls of the wood swell with furfuryl alcohol, which polymerizes within the cell walls. This treatment reduces the water absorption capacity of the wood, thus minimizing its tendency to deform with changes in moisture. The hardness and rot resistance of the modified wood are also improved compared to natural, untreated wood. The furfuryl alcohol used is obtained through the hydrogenation of furfural from biological agriwaste residues, such as husks and bagasse.
