Composition & manufacturing process Flax shives from the stalk of the flax plant comprise the bulk of flaxboard and are prepared in a mechanical chipper and can also contain other raw materials such as particles of wood (wood, flakes, chips, shavings, saw dust and similar materials). These chips are compressed and are generally bound together with synthetic resin systems such …

Composition & manufacturing Following storage for at least 3 months, the debarked softwood logs of selected species are reduced to flakes some 10 to 30 mm in length and 0.2 to 0.3 mm in thickness using drumknife flaking machines. After passing through a hammermill, the flakes are separated into surface and core material by screening, and are then mixed with …
