Question 1 Report
A furniture manufacturer selects MDF for a set of kitchen cupboard doors that will be spray painted in a gloss finish.
(a) State what the letters MDF stand for. [1]
(b) Describe how MDF is manufactured. [2]
Answer Details
(a) MDF stands for Medium Density Fibreboard. [1]
(b) MDF is manufactured by first breaking down wood into very fine fibres using a mechanical defibration process. [1] These fibres are then mixed with a synthetic resin adhesive (typically urea formaldehyde), formed into a uniform mat, and compressed under high temperature and pressure in a hot press. The heat cures the resin, bonding the fibres together to produce a dense, flat board with smooth surfaces on both faces and consistent density throughout its thickness. [1] The result is a homogeneous material with no grain direction, unlike natural timber.
