MDF board, Plywood & particle board
MDF, Plywood & Particle board comparison note
Wood fibers got by breaking down hardwood and softwood residuals are combined using wax and resin and heat pressed Thin sheets of veneer are glued together Structure Uniform, smooth and free of knots and grain patterns. Odd number of layers with grains of adjacent layers at right angles to each other. Face veneers are higher grade than the core veneers.
Safety hazards Use of urea-formaldehyde and phenol-formaldehyde resin which are carcinogenic in very high concentration Use of urea-formaldehyde and phenol-formaldehyde resin which are carcinogenic in very high concentration Uses Cabinet construction, crafts, Mouldings/trim, shelving (bookshelf sliding) Roofs, Walls, Subfloors, Boxes, Packages, Sports equipment, Musical equipment, Playground equipment, High-end loud speakers.
While MDF is generally cheaper than plywood, it is not as hard and can sag under heavy weight. MDF doesn't handle moisture very well, either, so it is more suited for indoor use such as in furniture. Moisture also affects the strength of plywood; exterior glued plywood can be used outdoors, but it works best when moisture content remains low.
Comparison between MDF & Particleboard
MDF is short for medium density fiberboard. MDF and particleboard are two forms of inexpensive wood-based sheet goods used by home and furniture builders, sometimes as substitutes for plywood.
Construction:
Very fine particle waste wood products, much more like layers of paper than wood, make MDF. Particleboard comes from very coarse sawdust mixed with special glues.
- Water-Resistance:
MDF is reasonably water-resistant, although you do not want to expose it to water if you can avoid it. Particleboard will soak up water easily, lose its stability and can fall apart.
- Appearance:
MDF has a very smooth texture and does not need edge banding; it also takes finishes well. Particleboard simply does not look good—any exposed edges will need to be finished, as will its flat surfaces.
- Building Use:
MDF is often used for built-ins. Particleboard is best used for under-flooring. Either material can become shelving and some types of furniture.
Warnings
Neither MDF nor particleboard is solid wood, so neither is as strong nor holds screws as well as solid wood. Some applications require special fasteners to use with these products. If you build with either material, use recommended glues in addition to any fasteners
