What is the MDF and Plywood?
MDF stands for medium-density fiberboard.
It is an engineered wood product. It is created by breaking down wood residuals into wood fibers. These wood fibers are then combined with wax and a resin binder. The mixture is then flattened and made into panels by applying high temperature and pressure.
Plywood, is a type of manufactured wood panel.
It is made by gluing together plywood layers, also called veneers. Plywood has various advantages over traditionally wood. It is flexible, inexpensive, workable and re-usable.
2.What is the advantages & disadvantages of MDF?
2.1.MDF is made up of separated fibers, so it to be denser than plywood, as well as stronger and denser than particle board.
2.2 MDF does not contain knots or rings like natural wood, thus it is more uniform in nature and is easier to cut and work with than traditional wood. MDF has a hard, flat, smooth surface that makes it ideal for veneering. MDF can also be glued, doweled or laminated.
However, MDF is similar to wood in the manner that it has the possibility of splitting while working with it, especially while installing wood screws without pilot holes.
Also, MDF does not hold smooth-shank nails well or fine-pitch screws.
Additionally, the MDF constantly emits urea-formaldehyde and other volatile organic compounds into the air for at least several months after manufacture. These compounds pose health risks at sufficient concentrations. Hence, it is recommended that MDF be painted on all sides of the finished product in order to seal in the urea-formaldehyde. Wax and oil finishes may also be used as finishes; however they are less effective at sealing in the urea-formaldehyde.
2.3.What advantages for Plywood?
Plywood is a type of manufactured wood panel. It is made by gluing together plywood layers, also called veneers. These veneers are glued together with adjacent plies having their wood grain at right angles to each other. This allows them to form a composite material. Cross-graining, i.e. having the wood grain at right angles to each other, reduces the tendency of wood to split, as well as reduces expansion and shrinkage. It also makes the strength of the panel consistent across both directions.
Plywood has various advantages over traditionally wood. It is flexible, inexpensive, workable and re-usable. Furthermore, it can usually be manufactured locally. Plywood is also resistant to cracking, shrinkage, splitting, twisting and/or warping. It also has a high degree of strength. All these attribute combine to make plywood one of the most widely used wood products.
