Features Of Clariant Exolit AP462 Flame Retardant

  1. Halogen-free, phosphorus-based intumescent flame retardant for enhanced environmental and regulatory compliance.

  2. Excellent thermal stability up to 300 °C, supporting high-temperature polymer processing such as injection molding and extrusion.

  3. Low water solubility and hydrolytic stability ensure consistent performance in humid environments and during long-term storage.

  4. High phosphorus content (≈22 wt%) delivers efficient char formation and superior flame inhibition in polyolefin systems.

  5. Good dispersion and compatibility with polypropylene (PP), polyethylene (PE), and thermoplastic elastomers (TPEs).

Typical Applications Of Clariant Exolit AP462 Flame Retardant

  1. Flame-retarded polypropylene for automotive interior components (e.g., dashboards, door panels).

  2. Wire and cable jacketing compounds requiring UL 94 V-0 rating at thin-wall thicknesses.

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

  4. Building and construction materials including insulation sheathing and ducting profiles.
