Calcium Silicate Board

High temperature calcium silicate board is composed of xonotlite hydrate and reinforced ﬁber, without asbestos. lt has the advantages of high temperature resistance, strong heat insulation performance, low bulk density, high speciﬁc strength, good durability, corrosion resistance, easy cutting and sawing, which can be widely used in energy-saving and thermal insulation engineering of industrial kilns

Performance:
A. Low thermal conductivity and good thermal insulation.
B. Good thermal stability and small shrinkage value when the temperature changes
C. Low density, small bulk density, less heat storage.
D. lts speciﬁc strength is the highest among the hard insulation materials.
E. lt has good durability and has no similar pulverization of ceramic ﬁber felt after long-term use.
F. No carcinogens – asbestos, sulfur, chlorine and other toxic substances and other low melting point organic binders.
