Is mineral fiberboard cement fiberboard?

No
Mineral fiberboard is not cement fiberboard. They are different in raw materials, production process, performance and scope of application.
Raw materials
The main raw materials of mineral fiberboard include rock wool, ceramsite, silicate, etc., which are processed by high temperature and high pressure, do not contain harmful substances, and are more environmentally friendly. The main raw materials of cement fiberboard are cement and fiber reinforcement materials, such as wood chips, waste paper, etc., which may contain substances that pollute the environment.
Production process
The production process of mineral fiberboard is high temperature and high pressure, which can ensure its strength and stability. The production process of cement fiberboard is relatively simple, and there are cases of uneven density and large strength differences.
Performance
Mineral fiberboard has a low density, good thermal insulation performance, and is not easily eroded by water and fire. Cement fiberboard has a high density, good water resistance and fire resistance, but relatively weak thermal insulation performance.
Scope of application
Mineral fiberboard is suitable for indoor partitions, ceilings, walls and other building materials because of its good thermal insulation performance and environmental protection. Cement fiberboard is suitable for indoor and outdoor walls, roofs, floors and other building materials due to its good strength and stability.
