Features Of Clariant Exolit EP Flame Retardant

  1. Halogen-free, phosphorus-based formulation ensuring low smoke and zero corrosive gas emission during combustion.

  2. Excellent thermal stability up to 300 °C, enabling compatibility with high-processing-temperature polymers such as polyamides and polyesters.

  3. Good hydrolytic stability and low water solubility, supporting robust performance in humid environments and long-term polymer processing.

  4. Low volatility and minimal plate-out tendency, resulting in enhanced extruder run stability and reduced maintenance downtime.

  5. UL 94 V-0 rated at low loading levels (typically 15–22 wt%) in glass-fiber-reinforced PA6 and PA66.

Typical Applications Of Clariant Exolit EP Flame Retardant

  1. Electrical and electronic components requiring UL 94 V-0 and CTI >600 V compliance.

  2. Automotive under-the-hood parts including connectors, sensor housings, and ignition system components.

  3. Consumer appliance housings and internal structural parts subject to stringent fire safety regulations.

  4. Industrial machinery enclosures where flame retardancy, mechanical integrity, and dimensional stability are critical.

  5. LED lighting fixtures demanding high comparative tracking index (CTI) and glow-wire resistance (GWIT ≥775 °C).
