HDF vs. MDF: (source: builddirect.com)

"… a high density fiberboard (HDF) for flooring is a type of engineered wood product. It's made from wood fiber extracted from chips and pulped wood waste. HDF for flooring is similar but much harder and denser than particle board or medium density fiberboard (MDF) for flooring. It has a density greater than 50 pounds per cubic foot or 800 kg per cubic meter. This makes for a perfect stabilizing material for laminate floors and engineered hardwood flooring."

"Medium density fiberboard for flooring, or MDF, is also an engineered product. It is made up of wood wastage fibers glued together with resin or glue under heat and pressure. It is similar to particle board but denser. MDF has a density of 600-800 kg/m³. It also doesn't warp or swell easily in high humidity areas like bathrooms or washrooms. Once again, these characteristics make it an ideal core layer material for laminate flooring and engineered floors."
