Asbestos-Free Micro-Porous Calcium Silicate Insulation Materials

I. Introduction
Asbestos-free micro-porous calcium silicate is a new type of thermal insulation material with a white, hard texture. It boasts features such as light weight, high strength, low thermal conductivity, resistance to high temperatures and corrosion, and is cuttable and sawable. These properties make it widely used in the insulation and fireproofing of equipment pipelines, walls, and roofs in industries such as power, cement kilns, metallurgy, petrochemicals, construction, and shipping. It is one of the best-performing rigid block insulation materials available. Our company specializes in producing asbestos-free micro-porous calcium silicate products and can customize special specifications according to actual needs.
Section II: Asbestos-Free Microporous Calcium Silicate Insulation Products Structure
Asbestos-free micro-porous calcium silicate thermal insulation products are a new type of lightweight, high-efficiency energy-saving block insulation material. It is a heat-resistant and lightweight block insulation material that is produced through a process of rational mixing, stirring, forming, heating, autoclaving, and drying, using powdered silicon dioxide, calcium oxide, fiber reinforcing materials, a small amount of additives, and a large volume of water.
Section 3: Key Features of Asbestos-Free Micro-Porous Calcium Silicate Insulation Products
Excellent fire resistance, capable of withstanding continuous thermal loads within the temperature limits.
2. Low thermal conductivity; due to the products' porosity exceeding 90%, they offer unparalleled insulating properties across the entire operating temperature range.
3. Lightweight and high-strength, its specific strength (compressive strength/density) is high among rigid thermal insulation products.
4. Excellent durability; no phenomenon of powdering or significant drop in insulation properties similar to ceramic fiber felt after long-term use.
5. High construction adaptability; products can be cut into various shapes using common woodworking tools. Also, they can be securely bonded with other components.
6. Safe and hygienic, free from asbestos, sulfur, and chlorine toxic substances. Non-flammable at high temperatures, emits no smoke or odor, and has corrosion-inhibiting properties on steel.
7. Our products, when exposed to water, retain their high-temperature resistance after drying. The silicate calcium board boasts excellent physical and chemical properties, good fire resistance, and can withstand continuous thermal loads below extreme temperatures.
Low thermal conductivity, over 90% porosity, and superior thermal insulation performance compared to other insulating materials within the reasonable operating temperature range.
8 times higher in strength. In thermal insulation products, the high-temperature-resistant calcium silicate board is lightweight yet boasts significantly higher specific strength compared to other insulation materials.
9 Durable. Long-term use in working conditions does not result in the same powdering phenomenon as ceramic fiber blankets, and operates stably under the excellent condition of high-temperature-resistant calcium silicate boards.

Installation is simple and convenient. No construction difficulties will arise; high-temperature-resistant calcium silicate boards can be easily cut with common tools and can be tightly bonded with other components.
11 Safe and Non-Toxic. The high-temperature calcium silicate board meets national standards and does not contain harmful substances such as asbestos, sulfur, or chlorine. It does not burn at high temperatures and will not corrode steel.
12. Performance is stable. Resistant to dampness; can be used normally after drying without affecting the product's construction performance.
At high temperatures, as long as the temperature does not exceed the maximum tolerance of the high-temperature calcium silicate board, the product itself will not experience any performance or structural damage. At the maximum temperature, the high-temperature calcium silicate board may exhibit slight softening. Exceeding the product's tolerance range will result in damage to its structural and performance properties.
