Free style expansion boards and co-extruding expansion boards
produced by PVC expansion boards production line have top-grade
quality, one complete of specs, can satisfy requirements of
different industries and win high reputation from clienteles.
PVC free style expansion boards have good performance of sound
insulation, sound absorption, heat insulation and heat
preservation.
PVC expansion boards can resist fire and can be used with high
security.
PVC expansion boards can resist damp, mildew and water, as well as
quakeproof.
PVC expansion boards are made of weatherable components, then the
color can exist long without aging.
PVC expansion boards are light, can be stored and moved
conveniently. Commonly used tools can be used for PVC expansion
boards.
PVC expansion boards can be drilled, sawed, nailed, planed and
adhered just like common wood materials.
PVC expansion boards fit for thermal moulding, heated bending and
folded processing.
PVC expansion boards can be welded according to common procedure
and can be connected with other PVC materials.
