Composition and How Magnesium Sulfate Boards Are Made

Materials and Structure

Magnesium sulfate sheathing boards use smart materials. Makers mix minerals and fibers to make them strong. The main part is magnesium oxide. It comes from magnesite or heated magnesium hydroxide. Fillers like perlite and vermiculite are added. These minerals get bigger when heated. This makes the boards lighter and helps keep heat inside. Wood fibers and fiberglass mesh make the boards stronger and flexible.

Here is a table that shows what is in magnesium sulfate boards:

The way magnesium sulfate boards are built helps them work well. They bend without breaking, do not soak up much water, and last a long time. These things make magnesium sulfate boards good for places that need strong materials.

Tip: Magnesium sulfate boards stay strong and keep their shape after freezing and thawing many times.

Improvements Over Magnesium Oxide Boards

Magnesium sulfate boards fix problems found in older magnesium oxide boards. Makers changed how they are made to make them better.

• Magnesium sulfate boards last longer in hard places. You do not have to change them often.

• These boards do not make metal parts rust. Magnesium oxide boards can have chloride, which causes rust.

• Magnesium sulfate boards handle water better. They do not swell, bend, or get white marks. This makes them great for bathrooms and basements.

• Tests show magnesium sulfate boards are stronger when bent. They meet tough rules like ASTM C1185 and C666.

• These boards stop mold and mildew. They work well in wet places.

• Magnesium sulfate boards help the earth. They make less carbon than Portland cement.

• They are very good at stopping water and fire. The boards stay strong even when wet.

Note: Magnesium sulfate boards have a strong whisker phase inside. This makes them safe for tall buildings and places that need extra strength.

If you pick magnesium sulfate boards, you get a product that fixes old problems and gives new benefits for building.

Features of Magnesium Sulfate Boards

Fire and Moisture Resistance

You want your building safe from fire and water. Magnesium sulfate boards protect well against both. These boards meet tough fire safety rules. The table below shows how they do:

Magnesium sulfate boards also resist moisture very well. They only take in 0.34% water. Mold cannot grow on them. You will not see swelling or warping. Other boards like plywood and drywall do not protect as much.

Durability and Strength

You need building materials that last a long time. Magnesium sulfate boards keep their shape in tough places. They do not swell, rot, or warp. The strong bonds inside make them very tough. You can use these boards in hot or cold weather. They do not crack or break easily. Their structure stops mold and mildew. This keeps your building safe and healthy.

Eco-Friendliness
