Microporous Calcium Silicate Board

Microporous calcium silicate board is an insulating material made primarily from mineral-based raw materials. It is typically used at temperatures below 650 °C.

This material offers multiple advantages, including excellent thermal insulation, high strength, and light weight, making it widely used in industrial, construction, and agricultural applications.

Advantages of mocroporous calcium silicate board:

  1. Excellent thermal insulation: Microporous calcium silicate board has very low thermal conductivity, which significantly reduces heat transfer and energy loss, helping to maintain stable internal temperatures.
  2. High mechanical strength: With its high strength, the board minimizes damage and waste during installation, reducing overall costs. Its superior strength also contributes to a longer service life.
  3. Non-combustible and fire-resistant: Made primarily from inorganic materials, microporous calcium silicate board is non-combustible and does not release harmful gases under high-temperature conditions, ensuring excellent fire safety performance.
  4. Lightweight and easy to install: The board’s low weight allows for easier handling and installation, while also reducing the overall structural load.

Typical applications of microporous calcium silicate board:

  1. Used for thermal insulation, heat preservation, and fire protection in industrial buildings and equipment.
  2. Applied in greenhouse and agricultural structures for heat insulation and temperature retention.
  3. Used in wastewater treatment equipment and plants, offering excellent corrosion resistance and high-temperature durability.
  4. Applied in interior wall decoration, ceilings, and flooring, providing thermal insulation, soundproofing, and fire-resistant performance.
