Features Of Clariant Exolit OP 1248 Flame Retardant

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

  2. Excellent thermal stability up to 300 °C, enabling compatibility with high-processing-temperature polymers.

  3. Low water solubility and hydrolytic stability, ensuring consistent performance during compounding and long-term use.

  4. Good dispersion in polyolefins and engineering thermoplastics, supporting uniform flame-retardant action without compromising mechanical properties.

  5. UL 94 V-0 rated at low loading levels (e.g., 20–25 wt% in PP), delivering efficient fire protection with minimal impact on density and processability.

Typical Applications Of Clariant Exolit OP 1248 Flame Retardant

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

  2. Electrical and electronic housings requiring UL 94 V-0 rating and RoHS/REACH compliance.

  3. Cable jacketing compounds based on polyolefin blends for low-smoke, halogen-free infrastructure wiring.

  4. Household appliance parts including washing machine drums, dryer housings, and microwave interiors.
