Introduction
The use of timbers in
furniture, construction site and interior decoration has
destroyed our forest badly in the last decades. How to reduce
logging to preserve the forests become the most important
environmental issues today. Artificial board such as plywood,
particle boards etc. seems to resolve the problems, but
the emission of benzene and formaldehyde had limited their
development. PVC as a substitute of timber is the new solution
in this century.
PVC foam board possesses
remarkable characteristics of light-weight, flame retarded,
strong, water repellant and chemical resistance. It is a
perfect substitution of timber but will not warp, swell
or decay in wet area. The board is manufactured to ISO 9001
quality management system and has obtained the Green Label
Award issued by National Environmental Protection Bureau.
Description
PVC foam board comprises
of PVC resin, foaming agent, stabilizers, lubricants,
plasticizers, fillers, impact modifiers, pigments and
other additives. The ingredients are thoroughly mixed
in the mixer and delivered to a silo from which they are
produced by an advanced patented technique employing co-extrusion
and foam technology. Depending on the content of plasticizers,
the finished product may be a foam board (>10%) or
a rigid board when the plasticizer is less than 5%.
PVC foam board is impermeable to water and is acid/alkali
resistance. Moisture will not cause leaching or efflorescence
and has no permanent effect on the board. The surface
hardness of PVC foam board is excellent when compared
to timber and its compressive strength is 1.7 times of
traditional timber. Depending on the pigment and pressing
machine, PVC board comes with different colors and patterns
only limited by the imagination of the designer.
PVC foam board is
light weight but strong. The board contains no formaldehyde
and is a green product which can be recycled. The board
is easy to work with by traditional wood working machine
such as drilling, nailing, screwing, planning and grinding
and can be decorated by painting, printing and film covering.
