Introduction
MultiPro is a calcium silicate board reinforced
with selected cellulose fibers and fillers. It is 100% free
from asbestos, inorganic fibers and formaldehyde. The board
is versatile and suitable for use in a wide range of internal
and semi-exposed external applications in building construction
project. It is an economical building board material with
fire-proofing property to replace concrete or block wall for
the construction of non-load bearing elements. Unlike most
plywood, MDF board, and gypsum boards, MultiPro is light weight,
strong and moisture resistance which 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
issued by National Environmental Protection Bureau.
Description
MultiPro is
a calcium silicate board off-white in color and has a smooth
finish on one side and a slightly textured reverse. It consists
of calcium silicate matrix reinforced with selected fibers
and special fillers. The board is cured under an autoclave
process where high pressure and high steam is induced to
ensure a complete chemical reaction. Thus provides the board
with excellent dimensional stability and chemical resistance.
MultiPro contains no water soluble additives and will not
rot, degrade or deteriorate. The board will absorb water
causing some loss of strength, which is fully recovered
on drying. Any staining on the panels caused by leakage
can be easily painted over. Moisture will not cause leaching
or efflorescence and has no permanent effect on the board.
MultiPro is non-combustible
when tested in accordance with ISO 1182:1990, GB8624 and
BS 476: Part 4, 5, 6 & 7. The board provides a degree
of thermal insulation and is resistance to continuous operating
temperature up to 80°C. MultiPro dry wall system complies
with both requirements of BS 476: Part 22, 1987 for 1 hour
fire rating partition in integrity and insulation and GB/T
9978 1999 for 2 hour fire rating partition with integrity
and insulation.
