    Severely cooked Masonite pulp was used as face material in three-layer experimental medium-density fiberboard (MDF). The core layer consisted of conventional MDF furnish with resin binder added. The faces were formed absolutely dry without additives of any kind. The three-layer mat was hot-pressed to overall densities ranging from 44 to 56 pcf. The faces had hardboard-like density, appearance, and characteristics. Face characteristics controlled overall bending strength and bending stiffness. Core characteristics controlled water absorption and linear expansion. This separation of characteristics into face and flexibility in board design core allows flexability in board design.
