Product Description

Magnesium Sulphate Board

Magnesium sulphate Board is a new generation board of magnesium Oxide Board which is also called mgso4 board.

it is made of pure Magnesium Oxide and Magnesium Sulphate,Reinforced by glass fiber mesh.

What’s difference between Mgo board and Mgso4 board?

Mgso4 board uses magnesium sulfate instead of magnesium chloride.magnesium sulfate makes Magnesium oxide panels incredibly waterproof by preventing moisture from absorbing back into the halogens in the board.

Note: We only Produce chloride-free Mgso4 board. You don't need to worry about Moisture regain and corroding steel and metal problems.

Our History

• 2012-2013

OCM began to produce and export chlorine free mgoboard 300 containers of Algerian military project. All boards apply on
steel frames.

• 2014

OCM was supplied to Spain and Italy Market with good reputation.

• 2015

OCM began to export chlorine free mgoboard to Chile and Colombia.

• 2016-2017

OCM entered to the Korean market and participate in government affordable housing projects in local and Southeast Asian countries, all using MgSO4 board in smart prefabricated system.

• 2018-2019

OCM focuses on researching and producing high level sanded mgso4 board and obtained a full set of test reports and
certificates for the Australian and New Zealand markets.

• 2021

OCM exported to Famous US company and approved by ICC audit factory

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.

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.
