MDF is a type of pressed wood produced from pure wood (in powder form) and then pressed with glue or synthetic chemicals.

MDF Board
What is MDF? As an industrial wood MDF brings a modern space from furniture, there are 2 types: normal MDF and moisture-resistant MDF. Let's learn more about this industrial wood.
What is MDF? MDF is divided into how many types?
MDF board
MDF Board
The term MDF stands for Medium density fiberboard, which means medium density fiberboard. But in fact, MDF is the common name for all three types of fiberboard products with medium density and high density (hardboard). To distinguish these three types, people rely on physical and mechanical parameters, parameters of thickness and surface treatment of the board.
MDF Wateroof
In terms of structure, MDF board has the basic components that are: wood fiber powder, adhesive, paraffin wax, wood protection agent (anti-termite, anti-mold), inorganic filler powder.
Dry process: glue, additives are sprayed into the dry wood pulp in a pre-mixer-dryer. The glued fiber powder will be spread out by a spreader-scraper into 2-3 layers depending on the size and thickness of the production glued boards. These floors are passed through a heated press. The press presses many times (2 times). The first time (preliminary pressing) for the upper layer, the second layer, the third layer The second pressing time is to press all three layers again. The heat setting is set so as to expel the steam and slowly solidify the glue. After pressing, the boards are exported, edge removed, sanded and graded.
Wet process: wood pulp is wetted with water to form a mat formation. They are raked and then spread on the press plate. Heat press once to preliminary thickness. The sheet is passed through a steam-heat lamination like a paper-making side to compact the two sides and remove excess water.

Applications of MDF in furniture
MDF is widely used in furniture manufacturing in general and office furniture in particular. In addition, it has the ability to replace natural wood with different advantages and disadvantages. Depending on the purpose of use, people use wood to produce furniture.
Bedroom furniture made of MDF industrial wood
Because this wood has poor water resistance, it ensures no elasticity or shrinkage at the same time with low product cost and uniform size board. Therefore, depending on the needs of using this wood, it is widely used in the production of tables, beds, wardrobes, home furniture, office furniture.
Advantages and disadvantages of MDF wood
Advantage
- Does not warp, shrink or rot like natural wood.
- Smooth flat surface.
- Easy to paint on the surface or stick other materials on top such as veneer, laminate, melamine.
- There is a large and uniform amount.
- The price is much cheaper than natural wood.
- Fast machining time.

Defect
- Poor water resistance with conventional MDF. Green MDF is more moisture resistant.
- MDF has only hardness not toughness.
- Cannot make carvings like natural wood.
- The thickness of the wood is also limited. If making high-thickness objects, many wood panels must be joined together.
Compare and distinguish MDF and MFC
Wood Core MFC
Wood MFC stands for Melamine Face Chipboard, which means chipboard (OSB, PB, WB) covered with Melamine. Wood used for making is from short-term crops such as acacia, eucalyptus, and rubber. These trees will be exploited and brought to the factory for processing by modern production lines.
The process includes: Chopping this wood into wood chips. Combined with glue and then pressed to create sheet thickness under high pressure strength. Then cover with a layer of Melamine for protection. This layer has the effect of creating aesthetics, anti-scratch, waterproof. The surface of the MFC sheet is in the form of a smooth, beautiful wood grain or metal imitation.
How to distinguish MDF, HDF and MFC
MDF Board
It is difficult to distinguish between MDF, HDF or MFC wood cores when they are finished with edge glued, painted, and painted products, however, you can apply a trick that is when the carpenter drills to remove the interior surface coating. If you want to install rails or hinges, you can take a close look inside and see if it's MDF, HDF or MFC.
Is MDF or MFC better?
MFCs have only one surface, which is Melamine, so they have to be edge glued to finish the surface. At the same time, the melamine surface is less human-friendly. Therefore, the common application of MFC is often for shelves, wardrobes, and kitchen cabinets. Also because MFC has higher bending resistance than MDF.
MDF is better used for beds, tables, and children's products because they are more aesthetically pleasing and more human-friendly (for MDF veneer).
Customers will always wonder if MDF is good?, as we have just shared, In general, MDF has good quality and can completely replace natural wood in the furniture industry in general, used for the right purpose. , properly preserved in the right environment, the lifespan of furniture products from MDF is very high: from 10 to 15 years of use.
How many types of MDF are there?
MDF wood is divided into 2 basic types: normal MDF and moisture-resistant MDF with green core.
Normal MDF and moisture-resistant MDF
Normal and moisture-resistant MDF will bring a modern space from affordable furniture and wood, so it is suitable for everyone. Hopefully with the above sharing, you will know how to use wood reasonably to take advantage of the advantages it brings.
