1.Decomposes at ~340°C, Magnesium Hydroxide for industrial use releasing water vapor to cool flames and forming a protective MgO char layer—ideal for silicone, rubber, and PVC-based fire seals. 2.Unlike halogen-based additives, Magnesium Hydroxide for industrial use suppresses toxic fumes and corrosive gases, critical for indoor and enclosed spaces . 3.Magnesium Hydroxide for industrial use Performs in silicone gaskets, intumescent strips, and expansion joints, enduring heat better than ATH. 4.Magnesium Hydroxide for industrial use Meets UL 94, EN 13501, and green building standards (RoHS/REACH) without bromine or phosphates. 5.Plastic grade Magnesium Hydroxide for Stearate or silane coatings improve dispersion in polymers, reducing viscosity issues at high loadings (50-65%).

Plastic grade Magnesium Hydroxide is an eco-friendly, non-toxic flame retardant widely used in fire seals, gaskets, and intumescent coatings due to its ability to suppress flames, reduce smoke, and delay fire spread.


Key Benefits in Fire Seals

1.Flame Retardancy

  • Magnesium Hydroxide Flame RetardantDecomposes at ~340°C,Plastic grade Magnesium Hydroxide absorbing heat and releasing water vapor to cool the material.

  • Magnesium Hydroxide Flame Retardant Forms a protective MgO layer, insulating the seal from further burning.

2.Low Smoke & Non-Toxic

  • Unlike halogen-based additives, Plastic grade Magnesium Hydroxide does not emit toxic fumes or corrosive gases, making it safer for indoor applications.

3.Thermal Stability

  • Magnesium Hydroxide Flame Retardant Works well in silicone, EPDM, and rubber-based fire seals, maintaining performance at high temperatures.

4.Acid Neutralization

  • Magnesium Hydroxide Flame Retardant Helps stabilize polymers (e.g., PVC-based seals) by neutralizing acidic degradation products.

5.Environmental & Regulatory Compliance

  • Magnesium Hydroxide Flame Retardant Meets UL 94, EN 13501, and other fire safety standards without using hazardous chemicals.


Conclusion

Flame retardant grade Magnesium Hydroxide is an effective, sustainable choice for fire seals, offering flame resistance, low smoke, and compliance with safety standards. For best results:

  • Flame retardant grade Magnesium Hydroxide Use surface-treated Mg(OH)₂ to maintain seal flexibility.

  • Flame retardant grade Magnesium Hydroxide Combine with ATH or synergists (e.g., zinc borate) for enhanced performance.
