Difference between mdf and plywood
What is MDF?
Medium Density Fiberboard (MDF) is an engineered wood product formed from wood fibers obtained
by breaking down hardwood and softwood using a defibrator. The wood fibers are then glued together
using wax and resin adhesive and made into panels by applying high temperature and pressure.
What is Plywood?
Plywood is made from good log called peelers. Thin layers are peeled from the wood by rotating it along
its horizontal axis. The sheets of veneer thus obtained are cut to the desired dimensions, dried, patched,
glued together and then baked in a press at 140 °C (284 °F) and 1.9 MPa (280 psi) to form a plywood
panel.
Strength and durability
MDF is not as hard as plywood and can be damaged easily when handled rough. It is not as stiff as
plywood and can sag with weight when used as shelves without reinforcement.
The cross graining of plywood improves dimensional stability by reducing expansion and shrinkage
equating. The strength of panels is consistent across both directions. Moreover, the odd number of
sheets reduces warping. Another advantage of plywood is that extreme cold does not affect its
dimensions or strength.
Disadvantages and Risks
Plywood
Plywood is porous and is susceptible to damage when exposed to water over time.
MDF
· MDF produces a large amount of dust when cut. It should be cut in a ventilated environment
and a respirator is advisable when cutting MDF.
· The panels are heavy.
· It is not water resistant.
· MDF is not as stiff and bends or sags under weight.
· MDF products emit urea-formaldehyde and other volatile organic compounds that pose health
risks at sufficient concentrations.
Cost
MDF is usually cheaper than plywood but a lot depends upon the grade of plywood. Higher grade
plywood is more expensive. In our company, if you want to make a < /productgrouplist-212642174/Food_Mall_Kiosk " target="_blank">food kiosk, we will use plywood
with laminate finish, however, if you make others kiosk, we will use MDF with baking paint finish, like
