Reconstituted Wood Panel Products

Ply
Plywood
Plywood is a sheet material made up of layers of wood
called “veneers”, consolidated under heat and pressure
using a synthetic resin as the adhesive,with the grains
of adjacent layers running at right angles to each other.

On account of its cross-laminated construction,
plywood has the following superior features:
  • High strength and stiffness in the
    longitudinal and transverse directions.

  • Excellent resistance to
    splitting, cracking and shearing.

  • Excellent dimensional stability.

  • High bonding strength between
    the constituent layers; much more
    than the natural bonding between wood fibres.

  • Flexibility — can be moulded into various
    forms and shapes.

  • Availability in large sizes without defects
    like knots, cracks, splits, etc.

Being a strong and rigid panel material, plywood is
suitable for a wide range of structural applications
in building construction, ship building, bus body
building, railway coach construction, etc. On account
of its close similarity to wood, and other conveniences
for manual working, it is also used extensively in
furniture and in building interior systems.

Block
Blockboard
Blockboard is a thicker sheet material
made up of a solid “batten core”
consisting of narrow battens of wood laid
side by side and further covered
with veneers on both sides as in plywood.
The battens are cut usually from timber
unsuitable for veneer production.
Blockboard is essentially a furniture panel.
In a modified form, it is also used
as a door shutter when it is
called a “Flush door”.

Particle

Particle Board
Particle Board is a sheet material
manufactured from small particles of wood
or similar lignocellulosic materials,
blended with a synthetic resin adhesive
and consolidated under heat and pressure.
The particles are produced from waste
wood in the form of lops and tops,
saw mill waste or agro-waste like baggasse,
rice husk, etc.

Medium Density Fibre Board (MDF)
MDF is a dry formed panel product
manufactured from fibres of wood
or other lignocellulosic materials combined
with a synthetic resin adhesive
and consolidated under heat and
pressure to a specific gravity
between 0.5 to 0.9.
