Particle board, also known as particleboard or chipboard, is an engineered wood product, belonging to the wood-based panels, manufactured from wood chips and a synthetic, mostly formaldehyde based resin or other suitable binder, which is pressed under a hot press, batch- or continuous- type, and produced.

The industry has traditionally shied away from using PF resins due primarily to their higher cost and much slower curing rate than UF resins. However, the press times for PF-bonded fiberboard can be substantially reduced by manipulating the fiber mat temperatures, molecular weight distribution of PF resins and pressing parameters.
Research published in 2017 showed that durable particle board can be produced from agricultural waste products, such as rice husk or guinea corn husk. [14] Particleboard is cheaper, denser, and more uniform than conventional wood and plywood and is substituted for them when the cost is more important than strength and appearance.
Although similar manufacturing processes are used in making all types of fibreboard, MDF has a typical density of 600–800 kg/m 3 or 0.022–0.029 lb/in 3, in contrast to particle board (500–800 kg/m 3) and to high-density fibreboard (600–1,450 kg/m 3). In addition, MDF typically has an MOR of 40 MPa and an MOE of 3 GPa.
[citation needed] At 3 ⁄ 8 inch (9.5 mm) thick, mahogany three-ply "wiggle board" or "bendy board" come in 4 by 8 feet (1.2 m × 2.4 m) sheets with a very thin cross-grain central ply and two thicker exterior plies, either long grain on the sheet, or cross grain. Wiggle board is often glued together in two layers once it is formed into the ...
Oriented strand board (OSB) is a type of engineered wood, formed by adding adhesives and then compressing layers of wood strands (flakes) in specific orientations. It was invented by Armin Elmendorf in California in 1963. [ 1 ]
Particle Removal is 99.97% down to 0.1 microns, plus this Energy Star-certified device boasts one of the highest Clean Air Delivery Rate (CADR) of 410 for fine smoke particles, dust and pollen ...
In response to the explosion of human population and material expectations in the 20th and 21st centuries, the company implements economies of scale, capturing material streams and creating manufacturing processes that hold costs and resource use down, such as the extensive use of medium-density fibreboard ("MDF"), also called "particle board".
