Plywood is a manufactured wood panel made from thin sheets of wood veneer. It is one of the most widely used wood products. It is flexible, inexpensive, workable, re-usable, plywood is used instead of plain wood because of its resistance to cracking, shrinkage, splitting, and twisting/warping, and its general high degree of strength.
Plywood layers (called veneers) are glued together with adjacent plies having their wood grain at right angles to each other to form a composite material. cross-graining has several important benefits: it reduces the tendency of wood to split when nailed at the edges, it reduces expansion and shrinkage equating to improved dimensional stability, and it makes the strength of the panel consistent across both directions. There are usually an odd number of plies so that the sheet is balanced_this reduces warping. Because of the way plywood is bonded (with grains running against one another and with an odd number of composite parts) it is very hard to bend it perpendicular to the grain direction.
Particleboard or chipboard is manufactured by mixing wood particles or flakes together with a resin and forming the mix into a sheet. The particles are first dried, after which any oversized or undersized particles are screened out, then the resin has been mixed with the particles, the liquid mixture is made into a sheet. The sheets formed are then cold-compressed to reduce their thickness and make them easier to transport. Later, they are compressed again, this process sets and hardens the glue. All aspects of this entire process must be carefully controlled to ensure the correct size, density and consistency of the board. The boards are then cooled, trimmed and sanded. They can then be sold as raw board or surface improved through the addition of a wood veneer or laminate surface.
Particle board is a manufactured wood product. It is actually quite environmentally friendly, as it is built from compressed shredded wood scraps and recycled wood, held together with a type of resin. It is cheaper and more dense than hardwood, but is not very strong or resistant to moisture. It also does not take paint (let alone stain) well.
To combat these deficiencies, most particle boards are covered with veneers glued onto the exterior surfaces made to look like the desired hardwood. To the untrained eye, a piece of furniture made from veneered particle board looks like a fine hardwood piece.
As with all manufactured wood products, there is a proper time and place for using particle board products. For instance, white, melamine covered particle board is well-equipped for use in interior tasks such as building closet shelves. The melamine is clean and doesn't require painting, and if affixed properly, will be stable and strong for a long time. I have used melamine coated particle board for numerous shop projects, and it holds up quite well.
