Calcium Silicate Board — High-Temperature Insulation & Fireproof Material for Industrial & Construction Projects
1. Product Overview of Calcium Silicate Board
Calcium silicate board is one of the most advanced, durable, and environmentally friendly inorganic insulation materials widely used in modern industrial thermal systems, building fire protection structures, and high-temperature equipment insulation projects. Manufactured through high-pressure molding and autoclave curing with premium siliceous raw materials, calcareous powder, and reinforced fiber components, the product features uniform internal structure, stable physical and chemical properties, zero asbestos content, and excellent overall performance under continuous high-temperature and harsh working environments.
2. Excellent High-Temperature Insulation Performance
Different from traditional thermal insulation materials such as rock wool, glass wool, and ordinary insulation boards, calcium silicate board possesses extremely low thermal conductivity, outstanding high-temperature stability, and superior pressure resistance. It can maintain stable insulation performance for a long time under continuous working temperature ranging from 650°C to 1000°C without deformation, shrinkage, softening, or structural damage. Even under repeated heating and cooling cycles, the board will not crack, peel, or lose its thermal insulation effect, ensuring long-term and reliable operation of industrial kilns, boilers, pipelines, and thermal equipment.
3. Premium A1-Grade Fireproof Safety Performance
In terms of fireproof performance, calcium silicate board reaches A1-level non-combustible standard, which is the highest fire resistance grade for building and industrial insulation materials. When encountering open fire or extreme high temperature, the material does not burn, does not produce toxic smoke, harmful gas, or molten dripping. It can effectively block heat transmission, prevent fire spread, and greatly improve the safety coefficient of buildings, industrial workshops, thermal power plants, chemical plants, and high-temperature production lines. This unique fireproof advantage makes it an indispensable material for fire partition walls, fireproof ceilings, ventilation duct insulation, and equipment fire isolation projects.
4. Superior Moisture, Corrosion and Aging Resistance
The product also shows excellent moisture resistance, corrosion resistance, and aging resistance. With low water absorption rate and stable molecular structure, calcium silicate board will not absorb moisture easily in humid environments, which avoids the problem of decreased insulation performance caused by dampness. It is resistant to most weak acid, weak alkali, and chemical gas erosion, and will not rust or corrode metal equipment and pipelines. Compared with organic insulation materials that are easy to age, deform, and decay, calcium silicate board has a super long service life and requires almost no frequent maintenance, greatly reducing the overall operating cost for enterprises.
5. Lightweight Structure & Flexible Construction Performance
Light weight and flexible processing performance are another core advantage of calcium silicate board. The material is light in density, easy to carry and transport, and will not cause excessive load on building structures and equipment supports. It can be freely cut, sawed, drilled, grooved, and shaped according to on-site construction requirements, which greatly improves construction efficiency and reduces construction difficulty. The flat and smooth surface of the board also enables perfect fitting with various thermal equipment and building structures, ensuring tight insulation and no heat loss gaps.
6. Wide Industrial & Construction Application Scenarios
Calcium silicate board is widely applicable in multiple industries and scenarios. In industrial fields, it is commonly used for thermal insulation of industrial kilns, rotary kilns, boilers, heat exchangers, high-temperature pipelines, power plant equipment, petrochemical thermal systems, metallurgical furnaces, and waste incineration equipment, serving as ideal backup insulation and heat preservation lining material. In construction fields, it is extensively used for building fireproof partitions, fireproof ceilings, wall insulation, ventilation and air conditioning duct wrapping, high-temperature room insulation, and public building fire protection projects.
