Features Of Albemarle Martinal ON-310 Aluminum Hydroxide Flame Retardant

  1. High-purity, surface-treated aluminum hydroxide offering excellent flame retardancy and smoke suppression.

  2. Optimized particle size distribution for improved dispersion in polymer matrices and enhanced mechanical properties.

  3. Thermally stable up to ~200 °C, enabling processing in common thermoplastics and thermosets without premature decomposition.

  4. Halogen-free formulation supporting compliance with RoHS, REACH, and other global environmental and safety regulations.

  5. Low abrasivity minimizes wear on extrusion and molding equipment during high-loading compounding.

Typical Applications Of Albemarle Martinal ON-310 Aluminum Hydroxide Flame Retardant

  1. Flame-retarded polyolefins (e.g., PP, PE) for wire & cable jacketing and automotive interior components.

  2. Low-smoke, zero-halogen (LSZH) compounds used in building & construction cables and conduit systems.

  3. Flame-retardant thermoset resins including unsaturated polyesters and vinyl esters for marine and transportation composites.

  4. Fire-safe elastomers and rubber compounds for transit seating, flooring, and sealing applications.

  5. Engineering thermoplastics such as polyamide (PA6/PA66) and thermoplastic polyurethane (TPU) requiring UL 94 V-0 rating.
