Features Of Quansheng FR-KSS Flame Retardant

  1. Halogen-free formulation ensures low smoke density and minimal toxic gas emission during combustion.

  2. Excellent thermal stability, maintaining performance up to 300 °C without significant decomposition.

  3. High phosphorus content enables efficient char formation and strong condensed-phase flame inhibition.

  4. Good compatibility with polyolefins, engineering thermoplastics, and elastomers without compromising mechanical properties.

  5. RoHS-compliant and REACH-registered, meeting global regulatory requirements for sustainable industrial use.

Typical Applications Of Quansheng FR-KSS Flame Retardant

  1. Wire and cable insulation and jacketing for low-smoke zero-halogen (LSZH) power and data cables.

  2. Flame-retardant polypropylene (PP) and polyethylene (PE) compounds used in automotive interior components.

  3. Electrical enclosures and housings for consumer electronics and industrial control systems.

  4. Thermoplastic elastomer (TPE) blends for flexible fire-safe seals, gaskets, and protective sheathing.

  5. Non-woven fabrics and spunbond materials for flame-resistant technical textiles in transportation interiors.
