• DESCRIPTION
Glass Fiber Reinforced Calcium Silicate Board is a high-end variant of Fiber Reinforced Calcium Silicate Board, utilizing glass fiber as the reinforcing material to overcome the brittleness and cracking tendencies of traditional calcium silicate boards while achieving superior mechanical properties. As a professional Glass Fiber Reinforced Calcium Silicate Board Manufacturer, Mindelun provides reliable insulation solutions for demanding industrial applications.
Also known as Glass Fiber Reinforced Microporous Calcium Silicate Board, this advanced insulation material combines the benefits of microporous calcium silicate with the enhanced strength and durability of glass fiber reinforcement. It can be viewed as an enhanced version of conventional calcium silicate board, offering improved structural integrity and resistance to cracking.
The manufacturing process is similar to that of standard calcium silicate boards, but the addition of glass fibers requires stricter control during raw material dispersion and molding. Key production steps include mixing raw materials with glass fibers to form a slurry, shaping the mixture through casting or pressing, and undergoing hydrothermal synthesis at high temperatures and pressures, typically around 170–200°C. This process promotes the formation of a tobermorite crystal structure, which contributes to the board’s strength and thermal insulation performance.
• PROPERTIES
Ø High Strength: Flexural strength is significantly enhanced. Research indicates that through process optimization, the flexural strength of low-density fiber-reinforced fireproof boards can reach up to 9.11 MPa.
Ø Class A Fire Rating: Classified as a Class A non-combustible material; it does not burn or emit toxic smoke when exposed to fire, making it an ideal choice for high-rise buildings and tunnels.
Ø Moisture and Water Resistance: Low water absorption ensures stable performance in humid environments; the board does not warp or rot, making it suitable for use in bathrooms, kitchens, and similar areas.
Ø Dimensional Stability: Extremely low rates of drying shrinkage and moisture expansion mean the board is resistant to cracking or warping caused by fluctuations in temperature and humidity.
Ø Non asbestos and non stick to aluminum.
Ø Weather resistance, dimensional stability (small dry and wet deformation), and high strength.
Ø High-temperature resistant (operating temperature up to over 1000°C): good thermal insulation and high strength.
• APPLICATION
Ø Interior Construction Interior partitions, ceiling panels, wall backing boards, kitchen and bathroom wall panels, basement applications, raised flooring (e.g., for server rooms)
Ø Exterior Construction Exterior wall panels, curtain wall backing boards, roof decking, composite thermal insulation wall panels
Ø Industrial Applications High-temperature insulation materials (e.g., ladle insulation, industrial furnace linings), components in contact with molten aluminum (transition plates, filter plates), fire-resistant door cores
Ø Specialized & Transportation Marine interior bulkheads, fire-resistant air ducts, tunnel fire protection systems, backing boards for prefabricated interiors, loft flooring panels
