OCM Fireproof Lightweight Mgo Eps Interior Wall Panel
Product Description
Lightweight MgSO4 Cement Board is an innovative, eco-friendly construction material that offers a range of benefits for modern building projects. This board is composed of magnesium oxide, magnesium sulfate, wood fiber, and perlite, which together create a panel that is not only lightweight but also highly resistant to fire, water, and mold . With its unique composition, the Lightweight MgSO4 Cement Board is known for its superior waterproof properties, preventing moisture from being reabsorbed into the board, which is a common issue with other types of boards . It is also recognized for its strength, flexibility, and resistance to impact, making it suitable for a variety of applications, including structural insulated panels (SIPs), decorative applications for internal walls, partitions, ceilings, and as underlay for floor and wall tiles. The board's chloride-free nature ensures it does not contribute to corrosion issues, providing a safe and durable solution for construction needs.

We have our own laboratory, 5 Professional R&D Staffs.which can carry out raw material evaluation, micro chemical reaction detection and physical performance evaluation. We research and design different density, strength, water absorption, combined structure of panel, flexural performance, nail holding force and fire resistance, and provide complete test reports.
Our factory has three production lines to make different grades of boards to meet the different application. The latest high automation equipment can produce high-Level products such as sanding board, shear wall and load-bearing subfloor. New equipment and facilities include automatic feeding and mixing system, plate forming process system, plate automatic demoulding system, sanded line and UV coating line. With an annual output of 2.1 million plates and about 3000 containers.

1.What is OCM® mgo board made of? What is the chloride content?
All mgo board consists of 3 elements, magnesium oxide, salt and crystal water.
The main component of OCM® Mgo board is MgO which is completely non-flammable and can be used for fire protection.
There are mainly two different types of salt:
- Magnesium oxychloride hydrated /Mgcl2 (steel corrosion risk)
-Magnesium oxysulfate hydrate/Mgso4(OCM mgo board)
OCM® MgO Board is a chloride-free Mgoso4 board. It uses magnesium sulfate instead of magnesium chloride.magnesium sulfate makes MgSo4 panels incredibly waterproof by preventing moisture from absorbing back into the halogens in the board.
According to The China Magnesium Oxide Board Industry Association issued a new standard of magnesia board industry, dissolvable (free) chloride ion content is below 5%, Content of Chloride is below 10%.
OCM mgso4 board Chloride content is below 0.012%, with reference to ASTM C871-11
you don't have to worry about "crying boards" when you use OCM® MgO Board on steel or metal frame.

2. Is OCM® Mgo board waterproof?
OCM® Mgo board is considered to be moisture resistant, but during prolonged exposure, moisture can affect it and it will
experience hydrothermal expansion. When used outdoors, Mgo board should be covered or coated to protect it from the environments, we can do waterproofing before leaving the factory, such as adding waterproofing elements or sealing with UV paint.
