INTRODUCTION TO MEDIUM
Medium-density fiberboard (MDF) is a composite wood product made of
compressed wood fibres, mixed with wax and resin.
MDF is similar to particleboard and hardboard,it is known for its strength,
smooth surface and edges and affordable pricing.
MDF has many applications and various sizes and comes with its share of
advantages and disadvantages, and is overall a very popular choice for many
Usually the panel will compressed to density of 0.5 to 0.8 specific
gravity in a hot press.
It varies in color from tan to chocolate brown.
Common thicknesses range from 1/4 in. to 1 in., but most home
centers carry only 1/2-in. and 3/4-in. Full sheets are oversized by 1
in., so a “4 x 8” sheet is actually 49 x 97 in. A full sheet of 3/4-in.
INTERIOR GRADE MDF
There are various types of MDF available. The most common, and
cheapest is standard interior grade material.
This is suitable for most internal applications where moisture is
not a consideration.
EXTERIOR GRADE MDF
Other grades of MDF include Moisture Resistant for use in areas
of moderate moisture.
Exterior grade MDF can be used externally for cladding or signage
For applications where weight is a prime consideration other, lower
densities of fibreboard are available.
APPLICATION OF MDF
Cabinet doors and drawer fronts
Internal cabinet carcasses
Lettering & Logos
Boxes and casework
All types of furniture
Less expensive than wood, easier to work with, more uniform and
more stable of a material.
Won't warp, check or crack and has no knots or surface grain
which makes it easier to cut, drill into, file or paint.
Can be painted to produce a smooth quality surface. Oil, water-
based paints and varnishes may be used on MDF
MDF may be dowelled together and traditional woodwork joints
may even be cut.
MDF may be glued together with PVA wood glue.. Veneers and
laminates may also be used to finish MDF
Big-dimensioned sheet, customer-required size.
Stable quality from overall-controlled production, some properties
better than natural wood, such as water-proof, fire-extinguishing, antipressing, less variability, etc.
Product surface satisfies direct use's requirement, saved much
Solid interior property, constant quality in the longitudinal and
Medium-density fiberboard is a heavier material than most solid
woods, and because it's so hard and dense, MDF may dull saw blades
and router bits more quickly than solid wood.
MDF also causes potential problems if the edges become
waterlogged since the material will swell.
There is a health danger from using MDF because most MDF panels
are made with resins that contain formaldehyde, a suspected carcinogen.
It is best to wear a respirator and safety goggles and provide adequate
ventilation when you cut or sand MDF to avoid inhaling the dust.
The cutting edges of your tools will probably dull quickly due to the
glue fibres in the MDF.
