Features Of Albemarle MARTINAL ON-906 Aluminum Hydroxide Flame Retardant

  1. High-purity aluminum hydroxide with controlled particle size distribution for optimal dispersion in polymer matrices.

  2. Endothermic decomposition at ~180–200 °C, releasing water vapor to cool the substrate and dilute flammable gases.

  3. Halogen-free formulation, supporting compliance with RoHS, REACH, and low-smoke zero-halogen (LSZH) requirements.

  4. Surface-treated with proprietary silane chemistry to enhance compatibility with polyolefins, PVC, and thermosets.

  5. Low abrasivity and excellent thermal stability up to 250 °C during compounding and processing.

Typical Applications Of Albemarle MARTINAL ON-906 Aluminum Hydroxide Flame Retardant

  1. Flame-retarded wire & cable compounds (e.g., LSZH jacketing and insulation).

  2. Fire-safe building materials including rigid PVC profiles, flooring, and ceiling panels.

  3. Thermoplastic elastomers (TPEs) used in automotive interior components and consumer electronics housings.

  4. Unsaturated polyester (UP) and vinyl ester composites for transportation and infrastructure applications.
