Question: what raw materials make mdf?
Answer: MDF is typically made up of 82% wood fibre, 9% urea-formaldehyde resin glue, 8% water, and 1% paraffin wax. and the density is typically between 500 kg/m3 (31 lb/ft3) and 1,000 kg/m3 (62 lb/ft3). The range of density and classification as light-, standard-, or high-density board is a misnomer and confusing.
