Features Of Clariant Exolit EP CCL Flame Retardant

  1. Halogen-free, phosphorus-based flame retardant offering excellent fire safety performance without generating corrosive or toxic fumes during combustion.

  2. Designed for high thermal stability—maintains integrity and efficacy in engineering thermoplastics processed at elevated temperatures (e.g., up to 320 °C).

  3. Provides outstanding electrical insulation properties, making it ideal for applications requiring UL 94 V-0 and CTI >600 V compliance.

  4. Offers excellent polymer compatibility and dispersion in polyamide 6 and polyamide 66 matrices without significant impact on mechanical strength or surface appearance.

  5. Supports sustainable manufacturing with low environmental persistence and no REACH SVHC listing under current regulations.

Typical Applications Of Clariant Exolit EP CCL Flame Retardant

  1. Electrical and electronic components—including connectors, circuit breakers, and housing parts for consumer and industrial equipment.

  2. Automotive interior parts such as fuse boxes, sensor housings, and under-hood components requiring stringent flammability and tracking resistance.

  3. Industrial automation housings and control units where long-term thermal reliability and arc resistance are critical.

  4. Power tools and household appliance casings subject to IEC 60695-11-10 needle flame and glow-wire ignition test requirements.

  5. 3D-printed functional prototypes and end-use parts in flame-retardant PA6/PA66 filaments for certified applications.
