Features Of Albemarle MAGNIFIN H5 Magnesium Hydroxide Flame Retardant

  1. High-purity magnesium hydroxide with low chloride and sulfate impurities for enhanced polymer compatibility.

  2. Optimized particle size distribution to support excellent dispersion in thermoplastics and elastomers.

  3. Halogen-free, non-toxic flame retardant that decomposes endothermically to release water vapor, suppressing combustion.

  4. Low abrasivity minimizes wear on processing equipment during compounding and extrusion.

  5. Thermally stable up to ~340 °C, enabling use in high-melt-index polyolefins and engineering resins.

Typical Applications Of Albemarle MAGNIFIN H5 Magnesium Hydroxide Flame Retardant

  1. Flame-retarded polypropylene (PP) for automotive interior components.

  2. Low-smoke, halogen-free cable jacketing and insulation compounds.

  3. Fire-safe thermoplastic elastomers (TPEs) used in consumer electronics housings.

  4. Flame-retardant masterbatches for wire & cable, construction membranes, and transportation materials.

  5. Environmentally compliant flame retardancy in polyethylene (PE) pipes and geomembranes.
