A process of thermal modification of pressurized wood with a medium moisture content was described in a paper by Burmester in 1973. [3] Today there are five different thermal modification processes. Finland produced Thermowood also known as Premium wood. France uses the Les Bois Perdure Retification process, the Netherlands uses the Plato ...
There is an extensive volume of literature relating to the chemical modification of wood (Rowell, 1983, 1991; Kumar, 1994; Haque, 1997). Drying timber is one method of adding value to sawn products from the primary wood processing industries.
Wood chemistry, whose primary focus is the analysis of the chemical constituents comprising wood, with specific emphasis on cellulose, lignin, hemicelluloses, and extractives, as well as on the various products derived from these components. It is also explores potential uses for pulp and paper production, the utilization of wood and wood waste ...
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 [ 1 ] to enhance the physical, mechanical and biological properties of wood.
Acetylated wood is a type of modified wood that is produced through a chemical modification process and does not contain any toxic substances. [1] It produced from a chemical reaction (named as acetylation), involving acetic anhydride and a modification process to make wood highly resistant to biological attacks by fungi and wood-boring insects and durable to environmental conditions.
Heat bending is the procedure of bending wood into different curves and shapes using moisture and a bending iron. By placing the wood into water, the moisture and heat from the bending iron will reform the structure of the wood, reorganizing the fibers of the wood to prevent the wood from springing back to its original state.

Impregnation resins are slightly viscous, organic liquids that are used in the forest products industry for wood modification. They typically contain formaldehyde and are composed of dimers and trimers of the main molecule. These can become polymer solutions upon curing inside of a wood substrate, imparting stabilizing properties.
Arboform consists of the two most abundant natural materials: lignin (ca. 30%) and cellulose (ca. 60%). The remaining part is natural additives that function as plasticizers, dyes, antioxidants, fillers, etc. [4] It has a similar composition, appearance and properties to those of wood, but it can be melted upon heating and molded like a thermoplastic.
