Features Of Clariant Exolit OP 950 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-melt-processing polymers such as polyamides and polyesters.

  3. Low loading levels (typically 15–25 wt%) achieve UL 94 V-0 rating in reinforced engineering thermoplastics.

  4. Good compatibility with glass-fiber-reinforced polyamide 6 and PA66, minimizing impact on mechanical properties.

  5. Low smoke and low toxicity during combustion, contributing to improved fire safety and reduced corrosion in electrical components.

Typical Applications Of Clariant Exolit OP 950 Flame Retardant

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

  2. Automotive under-the-hood components including connectors, sensor housings, and fuse boxes.

  3. Industrial control units and power distribution modules exposed to elevated operating temperatures.

  4. LED lighting enclosures where halogen-free, low-smoke performance is mandated by regional safety standards.

  5. Consumer appliance parts subject to stringent fire safety regulations (e.g., IEC 60695, EN 60335).
