Hexagonal Plate Magnesium Hydroxide (MDH) is a high-performance, eco-friendly inorganic flame retardant featuring a unique lamellar (plate-like) crystal structure. Compared with conventional MDH, its hexagonal plate morphology provides superior dispersion, enhanced barrier effects, and improved mechanical properties in polymer systems.

Key Advantages

• Excellent Flame Retardancy
  Decomposes endothermically, releasing water to dilute combustible gases and suppress smoke generation.

• Unique Plate Structure
  The hexagonal flakes create a barrier effect, slowing heat transfer and improving char formation.

• Low Smoke & Non-Toxic
  Halogen-free and environmentally friendly, meeting stringent safety requirements.

• Enhanced Mechanical Performance
  Better compatibility with polymers, maintaining tensile strength and elongation.

• Good Processability
  Smooth particle surface and controlled particle size distribution enable easier compounding.

Applications

Hexagonal plate MDH is widely used in:

• Wire & Cable Compounds (LSZH)
  Improving flame resistance while reducing smoke emission.

• Rubber & Elastomers
  Suitable for EPDM, NBR, and other rubber systems requiring flame retardancy.

• Engineering Plastics
  Applied in PP, PE, EVA, and other thermoplastics.

• Construction Materials
  Used in insulation boards, coatings, and fire-resistant panels.
