Features Of Albemarle MARTINAL OL-111 Flame Retardant

  1. Halogen-free aluminum hydroxide (ATH) based flame retardant offering excellent thermal stability up to ~200 °C.

  2. Optimized particle size distribution for improved dispersion and compatibility in polymer matrices.

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

  4. Surface-treated grade enhancing interfacial adhesion with polyolefins, PVC, and thermoplastic elastomers.

  5. Low moisture content (< 0.3 wt%) supporting consistent processing and reduced risk of void formation.

Typical Applications Of Albemarle MARTINAL OL-111 Flame Retardant

  1. Flame-retardant cable jacketing and insulation compounds (e.g., LSZH formulations).

  2. Fire-safe building materials including ceiling tiles, wall panels, and decorative laminates.

  3. Transportation interior components such as automotive seat foams, trim parts, and under-hood non-structural housings.

  4. Electrical enclosures and housings for consumer electronics and industrial control systems.

  5. Thermoplastic elastomer (TPE) and thermoplastic polyurethane (TPU) applications requiring UL 94 V-0/V-1 compliance.
