Difference between MDF, woodfiber board and particleboard
MDF (medium-density fiberboard) is an engineered wood product made of fine wood chips. Fiber boards of the same thickness are manufactured from the wood, meant for felling, or wood wastes (chippings), that are milled to small fibers (chips), then subjected to high-pressure steam and fed to the rotating segments of refiner. All refined material immediately goes to the drier and subsequent glueing.
Products made of MDF can be installed in premises with a relative humidity of 80%, in comparison with 60% for wood products.
Particleboard is manufactured by hot compression of wood particles, mixed with binding agent and forming the mixture into a sheet. Particleboard raw material is any low-cost wood species, both softwood and hardwood. The use properties of particleboard mainly depend on density, shape and size of wood particles and also amount and quality of the binding agent.
There are particleboards of very low (350-450 kg/m³), low (450-650 kg/m³), average (650-750 kg/m³) and high (700-800 kg/m³) density with one, three and five layers.
It is not recommended to use particleboard for premises with high moisture.
Particleboard is a widely used material for the production of cabinet furniture, interior decorations, roof and partition constructions, etc.
Advantages: waterproof, strong, easy to handle. Particleboard tightly “holds” nails and screws, could be easily machined (cut, drilled, milled, etc.), glued and painted. One more particleboard benefit is a low price. That is why particleboard is the most widely used material for the fabrication of economy-class furniture: the majority of office furniture is made of particleboard.
Disadvantages: formaldehyde resins, which bind wood particles.
There are two types of particleboard: Е1 and Е2.
Particleboard is also heavier and less stronger than natural wood.
Wood fiberboard is manufactured by hot compression of uniformly milled wood mixture, impregnated with synthetic resins, with the inclusion of certain additives to the mass. The raw material for wood fiberboard is pulverized wood chips. To improve the properties of fiberboard, paraffin wax, colophony (to increase waterproof property), synthetic resin (to increase the board strength), antiseptics are added to the wood mixture.
