What properties does MDF exhibit?
MDF has many qualities that make it an ideal replacement for plywood or particle board. It is dense, flat, stiff, has no knots and is easily machined. Its fine particles provide dimensional stability without a predominant “grain” (as is the case with lumber). Unlike most plywoods, MDF contains no voids, and will deliver sharp edges with no tearout. MDF is very well damped acoustically thus making it an ideal material for speaker enclosures. Below are some typical values for the modulus of elasticity (in million pounds per square inch) and density (in pounds per cubic feet) for MDF, Oak, Pine and Fir Plywood.
