1. Introduction
With new materials and technologies, Improved Kam Chung magnesium oxide board has better performance and avoids the defects of traditional MgO board. We use an alkali-resisting glass fiber net to increase product strength, and new technologies to prevent the "crying" phenomenon. In that case, our products can be used in humid area and no need to worry about quality problem.
2. Application
Kam Chung Magnesia board is light in weight, resistant to fire, high in strength, good against moisture, thus suitable for a wide range of general building uses, such as ceiling, wall board and flooring for residential complex, hospital, school, workshop, warehouse, stadium or even furniture and billboard.
