Albemarle Martinal OL-104 Aluminum Hydroxide Flame Retardant

Albemarle Martinal OL-104 is a high-purity aluminum hydroxide flame retardant from the Martinal series, offering excellent thermal stability, low smoke generation, and halogen-free fire protection. Widely used in polyolefins, EVA, rubber, and cable compounds, it decomposes endothermically to release water vapor, suppressing combustion while minimizing corrosion and toxicity.

Features Of Albemarle Martinal OL-104 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. Low abrasivity, minimizing wear on processing equipment during compounding and extrusion.

  4. Thermally stable up to ~200 °C, supporting processing of engineering thermoplastics without premature decomposition.

  5. Halogen-free and RoHS-compliant, supporting sustainability goals and regulatory requirements for eco-friendly materials.

Typical Applications Of Albemarle Martinal OL-104 Aluminum Hydroxide Flame Retardant

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

  2. Wire and cable jacketing compounds based on low-smoke zero-halogen (LSZH) thermosets and thermoplastics.

  3. Flame-retardant rigid PVC profiles for building and construction applications.

  4. Engineering resin systems including polyethylene (PE) and thermoplastic elastomers (TPE).

  5. Non-halogenated flame-retardant masterbatches for injection-molded consumer electronics housings.
