Hard fiberboard
A hard fiberboard ( HB , from English hardboard ; also hardboard or Kabak board ) is a fiberboard with a density of over 800 kg / m³ and thicknesses of up to 8 mm. The board is made from lignocellulose fibers such as wood , straw or bagasse , whereby, in contrast to high-density fiberboard (HDF), a wet process is used for production. It is used for formwork , interior fittings , doors, furniture, packaging. Due to their material, the panels can be bent for processing.
They are usually made from wet fibers with more than 20% fiber moisture. The sheet is formed under high pressure at very high temperatures. Wet-pressed plates have a sieve mark on the back, caused by the sieve through which the water was pressed. The cohesion is mainly due to the felting of the fibers with each other and small additions of binding agents . Other additives can improve the material properties and make the panels insensitive to fungi, fire or water, for example.
Note
Artists often only speak of hardboard when a hardboard is used as an image carrier (example: “oil on hardboard”).
