Product Introduction

 

Hexagonal Platelet Magnesium Hydroxide is a high-purity halogen-free inorganic flame retardant, prepared using a special crystal-controlled process, featuring a regular hexagonal plate structure and a high aspect ratio. 

 

Why Hexagonal Platelet Structure Matters

 

Stronger Barrier Performance: The high aspect ratio structure effectively blocks the transfer of heat, oxygen, and combustible gases, improving flame retardancy and smoke suppression.

Superior Mechanical Properties: The plate-like crystals provide micro-reinforcement, enhancing material rigidity and dimensional stability.

Higher Formulation Efficiency: In some systems, it can optimize filler usage, improving overall material performance.

 

Core Advantages

 

Highly Effective Flame Retardancy and Smoke Suppression: Magnesium hydroxide undergoes endothermic decomposition at high temperatures, releasing water of crystallization. Combined with the plate-like barrier layer, this effectively reduces the heat release rate and smoke generation, improving the flame retardancy rating.

Excellent Thermal Stability: Decomposition temperature ≥330℃, suitable for high-processing-temperature systems such as PE, PP, EVA, and PA, and less prone to premature decomposition during processing.

Good Electrical Insulation: Excellent insulation properties improve the electrical safety of cables and electronic materials.

Enhanced Mechanical Properties: The plate-like structure improves material strength and dimensional stability, reducing performance losses associated with high filler content.

Environmentally friendly and halogen-free. Contains no halogens or heavy metals and complies with RoHS, REACH and global halogen-free regulations.
