Pressboard is a rigid, fiber-based sheet material manufactured from mechanically or chemically separated wood fibers (typically wood pulp) that are pressed together under high pressure and temperature. It's often used as a cost-effective alternative to solid wood, plywood, or other engineered wood products. The resulting sheet is generally dense and offers moderate strength, dimensional stability, and smooth surfaces, making it suitable for various applications. Variations in manufacturing processes lead to differing densities, thicknesses, and surface qualities. Pressboard's key characteristic is its affordability and suitability for applications where high strength or moisture resistance isn't a primary requirement. It's often edge-finished or laminated to enhance its durability or aesthetic appeal. The manufacturing process often involves the use of adhesives or binding agents, to hold the fibers together during and after compression, allowing for different applications.
