After years of quality and practical application improvement, OCM board is developed by magnesium oxide (MgO).
It is a type of MgO board, but it is much better than the general MgO board. No sweat or material corrosion.
OCM board is made of high-purity activated magnesium oxide, perlite, high-strength glass fiber mesh, non-woven fabric and circulating water, and then becomes a truly healthy material.
The following benefits will undoubtedly show you why you should use OCM Materials for construction and live in a stronger and safer house, where you can really enjoy the long-term energy saving effect and have a quieter and warmer environment.

 OCM board is more "environmentally friendly" than traditional drywall and fiber cement. It is the most environmentally friendly wood board in the 21st century.

  3 hours of fire resistance. Like a "fireman" on the wall.

It exceeds the test criteria presented in ASTM E136 and is classified as non-combustible.
6MM = Classification A
12MM = Classification A
OCM MGO board® exceeds the test criteria presented in ASTM E84 and is
classified non-flammable.

 100% mineral based and completely Non toxic and no off gassing

this natural mineral can resist fire, mold, mildew, and insects better than the harsh chemicals found in other boards.
 Reasonable Moisture Resistant makes your wall can breathe

OCM MGO board Moisture absorption
According to ASTM C1185-08(2012)
It makes people feel comfortable and healthy to live a breathable environment.
It Will absorb very little water, and will breathe it out without losing any structural integrity.
