Features Of Woojin CXB-2000H 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 (e.g., PP, PE, PA6), and elastomers.

  5. Non-migrating design provides long-term flame retardancy retention under mechanical stress and aging conditions.

Typical Applications Of Woojin CXB-2000H Flame Retardant

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

  2. Flame-retardant automotive interior components including dashboards, door trims, and seat frames.

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

  4. Building & construction materials such as rigid PVC profiles, ceiling tiles, and ductwork linings.

  5. Transportation interiors for rail and bus applications requiring UL 94 V-0 and EN 45545-2 compliance.
