MDF is made from very fine particles of wood. While MDF can be made from cutoffs of dimensional < style="font-size:16px;color:#000000;font-family:Times New Roman;">lumber, it more commonly is made directly from logs that aren’t chosen to be cut into directional lumber. These logs are debarked, with the cambium layer removed, and then chipped into fine pieces. The pieces are screened, and any pieces too large for use in the MDF are re-chipped. After removing impurities and washing, the fine chips are mixed with waxes and resins, then are pressed into boards. These boards are then dried, laminated, trimmed and packaged for distribution.
