Chipboard, sometimes called particle board, is a board made by compressing small pieces of wood with glue. The advantage of chipboard is that it can be made from wood pieces that would otherwise have been discarded, saving the unnecessary cutting of more trees in some wood applications not requiring a higher grade of lumber.
Manufacturing Process - Chipboard is made from forest by-products. When forests are cut or thinned the resultant sawdust is collected. Small pieces of wood, left from the milling process and unsuitable for other uses, are granulated into wood chips and added to the sawdust. The mixture is formed into a slurry using urea formaldehyde and other less toxic binders according to how and where the chipboard will be used. The slurry is then subjected to high heat and pressure which eliminates the liquid and forms the wood chips into panels.
