Overview of Antimony Trioxide
Antimony Trioxide (Sb2O3) is an inorganic compound commonly used as a synergist in halogenated flame retardants. It enhances fire resistance by promoting char formation and slowing down the combustion process. Its high thermal stability, low toxicity, and compatibility with multiple polymers make it a preferred choice in fire safety applications.
Applications Across Industries
Antimony Trioxide is utilized in numerous industrial applications due to its excellent flame-retardant properties:
- Plastics: Used in PVC, polypropylene, and polyester to improve fire safety.
- Textiles: Incorporated into fibers and coatings to enhance fire resistance.
- Electronics: Applied in cables, circuit boards, and connectors to prevent fire hazards.
- Rubber: Adds flame retardancy in automotive and industrial rubber products.
- Adhesives and Coatings: Integrated to reduce flammability in industrial coatings and sealants.
