CALCIUM SILICATE FIRE-PROOF BOARD
The range 280-450kgs/m3 of 1000 centi-degree Calcium Silicate Insulation Board has been developed to provide outstanding service in demanding fire-proof application such as industrial chimney and flue part contact fire directly. It also can bear load and support different from refractory backup insulation. Uses include fire-rated enclosures around structural steel, tanks,equipment,fire-rated walls and fire-proof doors.Double sanded surface finishing give a precise specification . Test report made in European authorized lab are available.
ADVANTAGE:
A.Pefect fire-proof performance: Its fire proof grade can reach 2-3 hours , completely meet the USD standard ANSII/UL1709-2007 Rapid Rise Fire Test of Protection Material for Structural .
B.Low thermal conductivity figures—Lowest conductivity provides top insulation thoughout its temperature range.
C.Good thermal stability—Xonotlite calcium silicate provides superior thermal shock resistance and stability withstand continuous heat up to its full temperature use limit with small linear shrinkage。its 8-11% crystal water content perform as a buffer to attacks the heat when fire happen.
D.Long service life—No pulverization such like ceramic fibre felt.
E.Easily machinable__ Loosen and fibre composition make the board can be macined by normal wood-working tools at slower speed , also electric saw,utilizing carbide or diamond tipped tooling.
F.Safe and clean operation—Free from asbestos,suiphur,and chloride, no toxic carcinogen.
