Description of Fiber Reinforced Calcium Silicate Board

Fiber-reinforced calcium silicate board is a new type of architectural and industrial board made from silica and calcium as primary raw materials, with a certain proportion of reinforcing fibers added. The board is manufactured through pulping, molding, and high-temperature, high-pressure steam curing. The addition of fiber reinforcement enhances the board’s strength and toughness, making it suitable for both architectural decorative purposes and industrial high-temperature insulation applications.

Fire-resistant, high-temperature stable
Moisture-resistant and mildew-resistant
Thermal and sound insulation
Safe, environmentally friendly, and asbestos-free
