FAQ

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.

3.What is the difference between OCM® mgo board and other mgo boards?

-OCM is new generation chloride free mgo board. Thickness 3-30mm.Max size 1220*3050mm.
-We are ICC Audit factory, Controlled from Raw materials to finished products are strictly inspected.
-OCM mgo has outstanding physical performance
.Standard strength 6mm> 20-35 Mpa, 12mm > 15- 20Mpa,18mm≥20-25Mpa.
.Minimum low water absorption rate <8-10%
. Chloride Content ≤0.012%
. Fire resistance up to 270mins.

4. Is OCM® Mgo Board safe product?

Yes. OCM® Mgo board is safer than many comparable building products. It is a mineral based product made with non-toxic ingredients. (See our test report of Asbestos content, TOVC) It is completely recyclable and resistant to mold, mildew, fungus and allergens. It is also free of carcinogens and silicas.

5.What dimensions are commonly used to define OCM® Mgo Boards?

OCM® Mgo Boards are sold in 4 × 8 ft,4x9 ft,4x10ft sheets other small size can customized and in multiple thickness from 3mm to 30mm.
