Product Description

Magnesium oxide board is a new type of green building materials and includes Magnesia-based substrate board and sanded board, which has the characteristics of fireproofing, non-combustibility, light weight, high strength, heat insulation, frost resistance, cold resistance, no corrosion and no deformation. Magnesia-based substrate can be directly painted, plastered and coated with latex paint, and can also be directly covered with film and veneered after sanding treatment, so it is widely used in the field of decoration. Magnesia-based substrate can be pasted with wallpaper, ceramic tiles, marble, granite, aluminum-plastic board, wood veneer, PVC and other decorative materials.
