...panel product manufactured from wood fibers combined with a synthetic resin or other suitable binder. The panels are manufactured by the application of heat and pressure by a process in which the interfiber bond is created primarily by the added binder. The typical density range for MDF is 31-50...

...panels are manufactured to a density of 31 pet (0.50 specific gravity) to 55 pcf (0.88 specific gravity) by the application of heat and pressure by a process in which the interfiber bond is substantially created by the added binder. Other materials may have been added during...
