Densified wood

cpc code 31520 covers the production of densified wood, a specialized wood product that has been compressed and treated to increase its density and strength. Densified wood is an important material in various industries, including construction, furniture manufacturing, and transportation. It offers enhanced durability, dimensional stability, and load-bearing capabilities compared to traditional wood products, making it a valuable resource in applications where high performance is required.

The production of densified wood involves a multi-step process. First, raw wood materials, such as softwood or hardwood, are cut and prepared. The wood is then subjected to high-pressure compression, which reduces its volume and increases its density. This compression process is often accompanied by the application of heat, which helps to plasticize the wood and facilitate the densification. Finally, the compressed wood is cooled and stabilized, resulting in a dense, durable material with improved mechanical properties.

The main inputs required for the production of densified wood include raw wood materials, such as logs, lumber, or wood chips. Specialized machinery, such as compression presses and drying equipment, is also essential. Additionally, the process may involve the use of various chemicals or additives to enhance the wood's properties or to facilitate the densification process.

Densified wood is primarily used in applications where high strength, dimensional stability, and resistance to wear and tear are required. It is commonly used in the production of 44200 Furniture and 44210 Wood containers, as well as in the construction of 23110 Buildings and 30300 Transportation equipment. The densified wood produced under cpc code 31520 may also be used as an input for other industries, such as 31510 Veneer sheets; plywood, laminboard, battenboard and similar laminated wood, 31530 Particle board and similar board of wood, ligneous materials, and 31540 Fibreboard of wood or other ligneous materials.
