what is MDF ?

- Jan 09, 2019-

      Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibres, often in a defibrator, combining it with wax and a resin binder, and forming panels by applying high temperature and pressure. MDF is generally denser than plywood. It is made up of separated fibres, but can be used as a building material similar in application to plywood. It is stronger and much denser than particle board. Meanwhile, because the surface of the medium density fiberboard is flat and easy to paste various finishes, the finished furniture can be made more beautiful.

Chinese Name: 中密度纤维板

Medium Density Fiberboard(MDF) is a non-woody plant fiber raw material. It is an artificial board made by slicing, cooking, fiber separation, drying and applying urea-formaldehyde resin or other suitable adhesive, and then hot pressing. Its density is generally in the range of 500-880 kg / cubic meter, and the thickness is generally 2-30 mm.

MDF was developed in the mid-1960s and has since grown at a high speed. The reason is that it has excellent physical and mechanical properties, decorative properties and processing properties.


Ingredient: wood or plant fiber other than wood.

Thickness: 0.5-0.88g/cm3

Manufacture: The wood or plant fiber is mechanically separated and chemically treated, and then incorporated into an adhesive, a water repellent, etc., and then formed panels by applying high temperature and pressure.

The technical standard parameters of Chinese first-grade medium density fiberboard are as follows:

(1) Board thickness deviation should be small, generally should be controlled at ±0.3mm.

(2) Thickness swelling rate of water absorption should ≤12%.

(3) Free formaldehyde content does not exceed 70mg/100g.

(4) Screw pull-out strength: vertical board surface ≥1150N, parallel plate surface ≥660N.

(5) Board static bending strength≥17.2MPa.



Mechanical Property

Since the fiber structure of the plate is uniform and the bonding strength between the fibers is high, the static bending strength, the plane tensile strength and the elastic modulus are better than the particle board. And the screw pull-out strength, water absorbency and thickness swelling rate is low.

Decorating Property

Because the surface of the medium density fiberboard is flat, it is easy to glue the planing materials such as thin wood, tissue paper and the finishing, which is very economical.

Processing Property

MDF can produce plates from a few millimeters to tens of millimeters thick which can replace any thickness of timber. It has good machining property, the edge of the board can be processed in any shape, and the surface is smooth after processing.

Due to its excellent performance and an effective way to make rational use of wood, Medium Density Fiberboard is one of the most promising products.

MDF has a uniform internal structure, good dimensional stability, small deformation, moderate density and mechanical properties.

It has a smooth surface and good machinability. It can be pasted with thin wood or patterns. It is very popular among household decoration and is often used to make furniture and partitions.

Uses : It may be used to make display cabinets, wall-panels and storage units.
