Features Of ICL FR-11 Flame Retardant

  1. Halogen-free formulation ensuring low smoke density and reduced toxic gas emission during combustion.

  2. Excellent thermal stability, maintaining performance up to 300°C in polymer processing environments.

  3. High phosphorus content enabling efficient char formation and flame inhibition in thermoplastics.

  4. Good compatibility with polyolefins, engineering plastics, and thermoplastic elastomers without significant impact on mechanical properties.

  5. RoHS-compliant and REACH-conformant, supporting global regulatory requirements for sustainable materials.

Typical Applications Of ICL FR-11 Flame Retardant

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

  2. Wire and cable insulation in low-smoke zero-halogen (LSZH) compounds.

  3. Electrical enclosures and housings for consumer electronics and industrial equipment.

  4. Thermoplastic elastomer (TPE) formulations requiring UL94 V-0 rating at thin wall sections.

  5. Non-woven fabrics and spunbond materials used in transportation seating and building insulation.
