1.Antimony trioxide for Polyolefin building materials Helps reduce smoke density compared to some phosphorus-based flame retardants, improving visibility and safety during fires.
2.Antimony trioxide for Polyolefin building materials Ideal for indoor building materials (e.g., cables, insulation, wall panels) where smoke toxicity is a concern.
3.Antimony trioxide for Polyolefin building materials Acts as a powerful synergist with halogenated compounds (e.g., PVC, chlorinated paraffins) to significantly improve flame resistance.
Introduction
Antimony trioxide for Polyolefin building materials (Sb₂O₃) is a highly effective flame retardant synergist widely used in building materials to enhance fire safety. When combined with halogenated compounds, it significantly improves flame resistance while maintaining material performance. This article explores its key applications in flame-retardant PVC pipes, PVC flooring, engineering plastics, and polyolefin building materials, highlighting its benefits and industry relevance.
1. Antimony Trioxide as a Flame Retardant in Building Materials
Antimony trioxide is not a flame retardant by itself but works synergistically with halogenated additives (e.g., chlorinated paraffins or brominated compounds) to:
Suppress combustion by forming antimony halides that interrupt free radical reactions.
Reduce flame spread by promoting char formation.
Lower smoke emission, improving safety in enclosed spaces.
Key Advantages in Building Applications:
√ Cost-effective compared to non-halogenated alternatives
√ High thermal stability (suitable for high-temperature environments)
√ Minimal impact on mechanical properties (retains strength & flexibility)
√ Compliance with fire safety standards (UL 94, ASTM E84, EN 13501)
2. Key Applications in Building Materials
