MDF
Range MDF panels are sold either in their raw form with a fine sanded surface or with a surface decorative overlay such as bonded melamine papers, vinyl, or wood veneers. The most common grades available are Standard and Moisture Resistant (MR). A range of sheet sizes are available with the most usual being 2400 x 1200mm, and 3600 x 1200mm. Various thicknesses are produced as shown in Table 1.

Mechanical and Physical Properties
In determining product quality, a range of properties are tested on regular production samples. These tests are chosen to predict in-service behaviour and generally include density, internal bond, bending properties, surface properties, formaldehyde emission and moisture resistance.
The Australian Standard AS/NZS 1859.2 gives details of the minimum properties of the various types and thicknesses of MDF products. Surface properties for decorative overlaid panels are described in AS/NZS 1859.3. Also consult our Data Sheets (downloadable under Publications on this site) for typical values of AWPA member produced panels.
Special test behaviour such as acoustic or thermal properties may be available from manufacturers.
