SOLID MAGNESIUM HYDROXIDE IN A ROCK FORM

The solid mineral  magnesium hydroxide, with the chemical formula Mg(OH)2  is a common alteration product of periclase in marble; a low-temperature hydrothermal vein mineral in metamorphosed limestones and chlorite schists; and formed during serpentinization of dunites. It is often found in association with serpentine, calcite, aragonite, dolomite, magnesite, hydromagnesite, artinite, talc and chrysotile.

Advantages of Magnesium Hydroxide

• Filler and Flame Retardant/Smoke Suppressant in one product
• Environmentally Acceptable
• Halogen Free
• Non-Corrosive
• Reduces Smoke Density
• Non-Volatile
• Largely Inert
• Thermally Stable up to 340º C and thereafter undergoes Endothermic Decomposition releasing Water 

What is Endothermic & Exothermic Reaction?

LDPE (Low density Polyethylene) is a hydrocarbon material which exhibits exothermic reaction by releasing energy  when exposed to heat.  Mg (OH)2 is a natural mineral which exhibits Endothermic reaction by absorbing heat when exposed to energy/ heat.

Alubond-Stone (FR A2) – Endothermic Reaction

Alubond–Stone ‘s choice of Magnesium Hydroxide as its prime core mineral is based on the following data.

Reactivity :

Magnesium Hydroxide is much more reactive than Alumina Trihydrate (ATH), whereas ATH releases the available water over a broad range (230º C to 430º C), Magnesium Hydroxide releases the available water over a much narrower range (330º C or 630º F to 430º C). In simple terms this compares to spraying a fine mist of water over a fire (ATH) as opposed to dousing the fire with a full bucket of water (Magnesium Hydroxide). The quick release of water enhances the flame retardant properties of Magnesium Hydroxide.

Water Release :

Magnesium Hydroxide releases water at a higher temperature than ATH. The higher temperature release is at a more critical point that reduces the spread of the flame.

Particle Shape :

Magnesium Hydroxide particles, if viewed under a microscope, are plate-like versus the spherical particles of ATH. These plate-like particles overlap one another similar to fish scales or roofing shingles. Pound for pound these plate-like particles offer much more exposed surface area than spherical ATH particles. Therefore more particles are directly exposed to the flame. Also, the plate-like particles provide more strength, flexibility and reinforcement in the finished product as opposed to spherical particles.

Particle Integration :

Magnesium Hydroxide is a natural mix of particles. There is particle penetration and integration within Magnesium Hydroxide rather than having ATH and calcium carbonate particles mixed side by side. This allows a better distribution of the fire retardant and smoke suppressant properties.

Stability :

Magnesium Hydroxide has stabilizing characteristics that tend to neutralize acid and toxic smoke. ATH does not provide these benefits.

Char Ash :

Magnesium Hydroxide during the burning reaction forms a “Char-Ash” in front of the flame, which suppresses the flame.

Physical Properties

• Physical properties such as viscosity cure rate, stress strain and durometer, suggest that magnesium hydroxide is virtually indistinguishable from ATH from a filler performance standpoint.
• Magnesium Hydroxide, because of its acid scavenging properties, can play a useful role in halogenated compounds by reducing acid gas emissions.
• By absorbing the heat, magnesium hydroxide prevents or delays ignition and retards combustion of polymeric materials.
