Fiberboard

Metal scraps such as nails can be removed with a magnet placed over a conveyor belt on which the chips move forward.

In the case of, for example, MDF (medium density fiberboard) and not particle board, chips are then steamed to soften them for defibration.

Small amount of paraffin wax is added to the steamed chips and they are transformed into fluffy fibers in a defibrator and soon afterwards sprayed with adhesives such as urea-formaldehyde (UF) or Phenol formaldehyde resin (PF).

Consisting of bio-based, secondary raw materials (wood chip or sugarcane fibers) recovered from within 100 miles (160 km) of manufacturing facilities, the binding agent used in this type of fiberboard is an all-natural product, consisting of vegetable starch containing no added formaldehydes.

Fiberboard, classified by ASTM C208, Standard Specification for Cellulosic Fiber Insulating Board,[4] has many benefits and is used in residential and commercial construction.

Applications include: Fiberboard is also used in the automotive industry to create free-form shapes such as dashboards, rear parcel shelves, and inner door shells.

These pieces are usually covered with a skin, foil, or fabric such as cloth, suede, leather, or polyvinyl chloride.
