Medium Density Fiberboard (MDF)
Medium Density Fiberboard is manufactured from fibers or fiber bundles produced from wood by a mechanical refining process carried out at elevated temperature.
Overview
A synthetic resin binder, typically urea formaldehyde, is added to impart strength properties and paraffin wax to provide protection against accidental water spillage. MDF is stronger and provides a better surface finish than particle board (PB). Sheet goods and finished parts are used in the manufacturing of fixture, display, slatwall, cabinet and furniture components.
Main Uses
The excellent properties of Medium-density Fiberboard make it widely used in furniture manufacturing, speakers, strengthened floor, wall panels for interior decoration.It can also substitute plywood in the use of vehicles, aircraft and other industrial and civil buildings decoration. After secondary processing, medium-density fiberboard can be used to produce floor slab, water-proof boards, fireproof panels, automotive and cabin ,shelves, non-load-bearing clapboard for housing and so on, replacing a lot of natural wood and have significant economic benefits.
Working Properties
Medium Density Fiberboard like other wood based products and many other building materials will respond to changes in relative humidity of the surrounding air. Board dimensions are closely related to moisture content. Conditions likely to change the moisture content above or below the 8-12% range normally applying at dispatch from the factory, may give rise to problems. Medium Density Fiberboard should be conditioned to reach the humidity level in which it is to be used. Moisture content will normally be in the range 10-12% when used in buildings intended for human occupancy.
