Features Of Clariant Exolit OP950 Fiber Flame Retardant

  1. Halogen-free, phosphorus-based flame retardant specifically engineered for polyolefin fibers.

  2. Excellent thermal stability up to 280 °C, enabling compatibility with high-temperature fiber extrusion processes.

  3. Low volatility and minimal migration, ensuring long-term flame-retardant performance in end-use textiles.

  4. Good dispersion in polypropylene (PP) and polyethylene (PE) matrices without compromising mechanical properties.

  5. Complies with major fire safety standards including UL 94 V-0 (at appropriate loading) and EN 1186 for food-contact-adjacent applications.

Typical Applications Of Clariant Exolit OP950 Fiber Flame Retardant

  1. Flame-retardant staple fibers for automotive interior textiles (seat covers, headliners, carpet backing).

  2. Industrial filter media requiring compliance with DIN 4102 B1 or ASTM E84 Class A fire classifications.

  3. Technical geotextiles used in tunnel linings and public infrastructure projects.

  4. Nonwovens for protective workwear in low-risk industrial environments.

  5. Carpet yarns for commercial and hospitality sectors meeting stringent building code requirements.
