MEDIUM DENSITY
FIBERBOARD
(MDF)
INTRODUCTION TO MEDIUM
DENSITY FIBERBOARD
(MDF)
DEFINITION
• 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 woodworkers.
CONT…
• Usually the panel will compressed to density of 0.5
to 0.8 specific gravity in a hot press.
• It varies in colour from tan to chocolate brown.
• Common thicknesses range from 1/4 in. to 1 in., but
most home centres 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.

TYPES OF MDF
EXTERIOR INTERIOR
GRADE GRADE
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 work.
• 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
• Display cabinets
• Exhibition plinths
• Lettering & Logos
• Exterior signage
• Exterior cladding
• Boxes and casework
• All types of furniture
ADVANTAGES
• 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
CONT…
• 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.
CONT…
• Stable quality from overall-controlled production,
some properties better than natural wood, such as
water-proof, fire-extinguishing, anti-pressing, less
variability, etc.
• Product surface satisfies direct use's requirement,
saved much processing cost.
• Solid interior property, constant quality in the
longitudinal and transverse direction.
DISADVANTAGES
• 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.
CONT…
• 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.
