Features Of Otsuka SPB-100 Halogen-Free Flame Retardant

  1. Phosphorus-nitrogen synergistic system enabling high flame retardancy without halogenated compounds.

  2. Low smoke and low toxicity during combustion, meeting stringent environmental and safety standards (e.g., UL 94 V-0, RoHS, REACH).

  3. Excellent thermal stability up to 300 °C, supporting processing in engineering thermoplastics.

  4. Good compatibility with polyolefins, polyamides, and thermoplastic polyurethanes (TPU).

  5. Non-migrating formulation ensuring long-term flame-retardant performance and surface integrity.

Typical Applications Of Otsuka SPB-100 Halogen-Free Flame Retardant

  1. Wire and cable insulation for building wiring and data transmission cables.

  2. Automotive interior components including dashboards, door panels, and seat frames.

  3. Electronics housings for consumer devices, power adapters, and LED lighting enclosures.

  4. Industrial conveyor belts requiring fire-safe polymer composites.

  5. 3D printing filaments (e.g., PA6/PA12-based) needing UL-certified flame resistance.
