12KPINEMDFPine Knotty Plain Sliced A/B MDF Core 1/2" 4x8
Knotty pine plywood has a relatively straight grain. The sapwood is light yellow to creamy white, with reddish brown heartwood.
The Medium Density Fiberboard (MDF) core is made in a production process similar to Particleboard (PBC) except that all of wood particles are small and uniform like sawdust. MDF offers great stability and is the least likely to react when subjected to a measurable change in temperature or humidity. It offers a very smooth, void-free surface for veneer faces.
MDF has greater strength and screw holding properties than particleboard and weighs around 100 lbs per 3/4-inch panel. It is used in cabinets, furniture, fixtures and molding and is highly recommended for thin panel applications such as door inserts for cabinets and paneling.
