Magnesium Hydroxide MDH-III-3 can be used in Electronic and electrical components, conveyer belt and construction materials and it can be modified by stearic acid and silane.
MDH-III-3 has achieved a qualitative leap on the basis of traditional magnesium hydroxide, not only maintaining excellent flame retardant and smoke suppression properties, but also reaching new heights in dispersibility, compatibility, and functionality.
The average particle size of MDH-III-3 is controlled within the range of 300-500 nanometers, and the particle size distribution is concentrated. Combined with a dedicated surface modification process, it can easily integrate into various polymer systems, significantly reducing the amount of additives while endowing the substrate with superior comprehensive performance.
The flame-retardant mechanism of this material is endothermic decomposition, which we can break down into three key points to explain to you.
The first point is heat absorption and cooling. At high temperatures (approximately 330 degrees Celsius), Magnesium Hydroxide MDH-III-3 decomposes and absorbs a large amount of heat, a process that lowers the surface temperature of the material.
Then the second and third key points are revealed: through decomposition, this flame-retardant material releases water vapor and generates magnesium oxide. Water vapor has a diluting effect on the combustible gases and oxygen in the combustion zone. Lowering the concentration can control the combustion process and speed. Meanwhile, the magnesium oxide forms a stable, high-temperature-resistant barrier, isolating oxygen and heat. These two factors combined control combustion.
