"210mm x 300mm x 3mm thick hardboard sheets. Hardboard is similar to particle board and medium-density fiberboard, but is denser and much stronger and harder because it is made out of exploded wood fibres that have been highly compressed. Consequently, the density of hardboard is 31 lbs or more per cubic foot It differs from particle board in that the bonding of the wood fibres requires no additional materials, although resin is often added. Unlike particle board, it will not split or crack. Boards are subject to a tolerance of +/-2mm length/width during the cutting process."
