Medium Density Fibreboard (MDF) is made from wood fibers extracted from wood residues and binded together with resins and wax at high temperature and pressure.
MDF was invented in the 60s in the US and in the 90s became widely adopted worldwide. The largest producer worldwide is China, followed by Germany and the US but manufacturers of MDF can be found in all continents except Africa.
