What is the difference between medium density fiberboard and high density fiberboard?

In: Building and Carpentry, Flooring [Edit categories]

Answer:

The differences between medium density and high density fiberboard (mdf and hdf) do vary slightly between manufactures. These are some general facts.

MDF is a product of soft woods that are broken down by a defibrator, added to wax and resin, and formed from heat and pressure. The majority of the wood comes from saw dust. It is moderately resistant to termites and mold. It can be quite moisture sensitive.

HDF is made in a similar process as MDF, but is much more dense and made from exploded wood fibers and quite a bit more pressure. HDF is highly resistant to mold and infestation and not nearly as sensitive to moisture as MDF.
