6mm Fiber Cement Board

DESCRIPTION
The raw materials of fiber cement board are cellulose fiber, silicate cement, quartz sand, water and some additives. It''s a kind of high-tech product which formed through accurate dosing by computer program,
Hatschek craft and compressed by 14000tons hydraulic machine and autoclaved under high temperature and pressure. It''s 100% free of asbestos, formaldehyde, benzene and other harmful substances and with excellent performance like high strength, large size, light weight, fire and water proofing, green and environmental friendly, high efficient and energy-saving. Therefore, this kind of new material is vigorously developed and recommended by the country.
