Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibre, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure. [1] MDF is generally denser than plywood.
In the dry-process waste timber is dried and ground up into fibres, then mixed with a synthetic glue called PMDI (polymeric methylene diphenyl diisocyanate) is a polyurethane based glue which is used in fairly small quantities (3-4% by mass). This is essentially the same glue use in OSB and MDF.
