Product Description
1100℃ High Density 270kg/m³ Calcium Silicate Board - Hydrophobic Material for Boiler and Furnace Applications
Driven by global "carbon neutrality" goals and stricter industrial safety regulations, the thermal insulation industry is evolving toward higher efficiency, safety, and environmental sustainability. High-temperature industrial equipment requires materials that withstand extreme heat while offering both excellent insulation and mechanical strength.
Microporous calcium silicate board uniquely meets this demand with a maximum service temperature of up to 1000°C, a thermal conductivity as low as 0.06 W/(m*K), and non-combustible, asbestos-free properties. It has become an indispensable material for energy conservation and safety assurance in energy-intensive sectors such as power generation and petrochemicals.
Calcium silicate board is characterized by high-efficiency thermal insulation (low thermal conductivity), excellent high-temperature stability (no deformation), high compressive strength, and non-combustible, asbestos-free composition. Available in boards, pipe sections, and shaped parts, it is primarily used for thermal insulation of high-temperature pipelines, reactors, and kiln backings in power, petrochemical, and metallurgical industries, as well as for fireproof bulkheads in shipbuilding.
