What is MDF?


       A Medium-density fibreboard defines a Fiberboard. as a sheet made of fibers mixed with synthetic formaldehyde resin. or other suitable daily binders under heating and pressure. To improve the wood fibres performance, additives can used in the production process. MDF wood can produced from waste wood and recycled wood to maximize the uses of MDF wood.


      The Low-density fiberboard performance surface is smooth. uniform, compact, no scar, easy to paint. especially suitable for direct printing and veneer.  MDF board coatings can used as advanced decorative products. such as stereo speakers, load-bearing gears and molded parts. full-size MDF panels and good strength are also the main advantages of MDF furniture. 


       The precision tolerance of MDF Engineered wood is small in cutting process. which can replace solid wood and used in indoor and other new application fields. Standard product standard ANSI 208.2 MDF veneer industry standard. This standard classified according to density. 9 kinds used indoors or outdoors, and 4 kinds of product grades determined. The properties determined in the standard include physical properties, machinability. dimensional tolerances and aldehyde emission limits


      The MDF wood on other hand is also an engineered product. which made of wood wastage fibers attached together with resin. or glue under heat and pressure. It is like molecule board yet denser. MDF has a thickness of 600-800 kg/m³.


      It likewise doesn't twist or swell in high moistness zones. like restrooms or washrooms. By and by. these attributes make it a perfect center layer material for overlay flooring. and designed floors.


      The MDF wood used for making cabinetry, storage units. wall panels, furniture, shelving, decorative molding, and doors. Moreover, MDF is also used in acoustic enclosures including; sub-woofers and loudspeakers. due to its insular qualities in sound and heat.


 MDF panel Advantages


-Carpenters find it easy to work with

-The board can molded 

-Medium density

-Less expensive than hardwood and solid wood.


MDF board Disadvantages


-MDF does not have good strength. when compared to solid wood so make sure it is not used in applications. where heavy load  expected to be borne by the board. 

-MDF boards also do not have very good holding strength for nails/screws. If a furniture piece needs to moved or dismantled. and then rebuilt then the MDF board might loose the grip on the nails.

What is HDF?


      High-density fibreboard (HDF) is a wood board with a density of 750-930 kg/ m3. made of wood or other plant fiber, prepreg, or other suitable adhesive by hot pressing. It has a dense and smooth surface, a uniform core layer. and the surface and edge of the plate have good mechanical properties. and shaping properties. It is an ideal substitute for natural board.

      Also known as hardboard, a high thickness of ground surface is a kind of designed wood item. It made of wood fiber extracted from chips and pulped wood waste. The HDF is comparable but harder and denser than molecule board. or medium thickness for deck.


     It has a greater density than 50 pounds per cubic foot or 800 kg per cubic meter. That’s what makes this material a perfect stabilizing material for laminating floors. and engineered hardwood flooring.


       Unlike other types of fiberboard for flooring. this material cannot used outside since it has an ability to absorb water.


 It has the following features and functions

1.HDF Hardboard  density board is easy to complete. The various coatings can coated on the density board. and the density board is the preferred base material of the paint effect.

2. All kinds of wood skin. adhesive film, decorative board, light metal sheet, melamine board. and other materials can glued to the surface of the density board.

3. Excellent physical property, uniform material and no dehydration problem. High density board qualitative range of HDF Board (wood) is a board that divided into low density, medium density. and high density according to density.


 HDF board Advantages


-HDF comes with a smooth surface.

-HDF is High density board has more strength compared to MDF and Particle board

-Great solution for indoor and outdoor furniture, wall paneling.  furniture, room partitions, and doors. 


HDF Disadvantages


-HDF is the best board when compared with particle board and MDF. 

-Still a lot of carpenters prefer wood block board compared to HDF as they are more confident. about the nail holding capabilities of natural wood. whose blocks used to build the block board 


MDF vs HDF


1,density


      MDF (medium density fibreboard) with thickness from 1: 4 "to 1: 1 × 8" painted. printed or laminated, machined or manufactured by the components of your choice. The density board divided into low-density, medium-density and high-density according to the density. The fiber density board is a kind of artificial board made of wood fiber. or other plant fiber, or other suitable adhesive. So the essential difference between the mid-and HDF is the difference in density.

     The thickness of HDF (high density fiberboard) is 3.0 mm (1 ≤ 8 inches), 4.8 mm (3 ≤ 16 inches) and 5.5 mm (7 ≤ 32 inches). The density of high density fiberboard is higher. than that of medium density fiberboard.

      In fact, medium density fibreboards defined as fibreboards with a density of 0.45-0.88 g/ cm3. and fibreboards with a density of greater. than 0.88 belong to high-density fibreboards. Different people have different understanding of the specific division of medium-and high-density fibreboards.

 

2.Environment grade


      high grade mdf with different densities are generally better than those with higher densities.  but if they combined with environmental standards. they need to considered as a whole, because the higher the density, the more glue used.hdf board price and mdf price also not same

 

low density fibreboard


3. Usage


       Medium density fiberboard (MDF) has higher strength. and better surface finish than particle board . Plates and finished products used to make fixtures. displays, panel walls, cabinets and furniture parts. Transparent UV surface treatment and custom color matching transparent coatings provide designers, architects. and workshop planners with more options and melamine and laminate colors. In the case of traffic congestion, HDF is the preferred furniture, such as hotels, cinemas, government offices, etc. It also appears in the form of perforation and is used to hang various tools in the workshop. Because it is more moisture-proof, it is used as the core material of reinforced wood flooring.


      HDF it is an ideal base for storing fixing device, display board. This material is an ideal substitute for low cost tempering paperboard. HDF molding line has a large motherboard size and its output is better than that of single door press.


      MDF wood chips is mainly used to make shelves for furniture, cabinets and storage units. They are widely used in decorating walls and reliefs. Transparent partition also achieves modern or traditional appearance by carving medium density fiberboard.


4. Price


       high density fiberboard wood fiber is expensive as compared to the medium density fiberboard, as more pressure is applied during the manufacturing process. medium-density fibreboard MDF is cheaper than HDF, but is more expensive than board.


5. Live time


       HDF composite wood is a very durable material that can be used for many years without damage. MDF wood item can last up to 10 years in a dry environment. Laminated natural wood wood product MDF can be used for 15-20 years and must be replaced.


6. application


      There are different grades of MDF to suit different applications. and one of the key differentiating factors is the density of the MDF. The MDF we use (follow link for more information) is, as far as we can establish, the best MDF available for our purpose. Standard-grade MDF has a typical density of 680kg/m3 – 730kg/m3. whereas the moisture resistant MDF that we use is a premium grade and has a density of 800kg/m3.


     The more compact the fibres are, the less likely it is that the MDF will become ‘furry’ when the profile machined. If MDF does become furry it can lead to imperfections in the paint finish. as loose fibres get trapped by the moisture in the primer or paint and harden as it dries.

    

Skirting boards need to be as durable as possible to withstand knocks. and bumps from furniture and people over time. A denser board will have a greater resistance to damage, meaning it will last longer.


      High Density Fibreboard sounds like. it should  be MDF (medium density fibreboard) with a higher density. Thus, it is easy to see why some people may think this to be the true state of things. The name does in fact make it sound superior to MDF. because density is important (as established) and HDF has a greater density than MDF. The truth is that HDF. and MDF are completely different products for different purposes.

Buying Tips 


        Fiberboard has many benefits, such as being pest-resistant and easy to work with. There are many characteristics you should note. though, before choosing to buy any amount of MDF or HDF for your project.


-MDF/HDF does not have good holding strength when compared to real wood. If used for furniture items that need to dismantled/reassembled, it may not be your best choice.


-MDF/HDF cannot come into contact with water, as it will make the fibers swell and damage is very hard to repair. Do not use for outdoor projects.


-Because of the formaldehyde used in their construction, MDF. and HDF are less than real wood or other wood alternatives. While there are restrictions on formaldehyde amount. and the risk of out-gassing is lower with HDF, it is still a risk.


Which one suitable for Skirting boards


      High Density Fibreboard sounds like. it should be MDF (medium density fibreboard) with a higher density. Thus, it is easy to see why some people may think this to be the true state of things. The name does in fact make it sound superior to MDF because density is important (as established). and HDF has a greater density than MDF. The truth is that HDF. and MDF are completely different products for different purposes.


     The more compact the fibres are, the less likely it is that the MDF will become ‘furry’ when the profile machined. If MDF does become furry. it can lead to imperfections in the paint finish. as loose fibres get trapped by the moisture in the primer or paint. and harden as it dries.


   Skirting boards need to be. as durable as possible to withstand knocks and bumps from furniture and people over time. A denser board will have a greater resistance to damage, meaning it will last longer.
