Some organic flame retardants are commonly used as substitutes for antimony trioxide. Here are some common alternatives:
1. Aluminum hydroxide: Aluminum silicate is an inorganic flame retardant commonly used in materials such as plastics and rubber. It has good flame retardant performance and can effectively suppress the combustion process.
2. Ammonium phosphate: Ammonium phosphate is an inorganic salt commonly used as a flame retardant. It can slow down the combustion rate and improve the fire resistance of materials.
3. Nitrogen based flame retardants: Nitrogen based flame retardants are a type of organic compounds with good flame retardant properties, such as cyanates, nitrile flame retardants, etc. They can dilute the oxygen near the burning object by releasing nitrogen, thereby reducing the combustion rate.
4. Phosphorus based flame retardants: Phosphorus based flame retardants are a class of organic flame retardants widely used in plastics and rubber. They can improve the fire resistance of materials by suppressing smoke and heat release during the combustion process.
These substitutes can to some extent replace antimony trioxide, provide good flame retardant performance, and do not pose potential environmental and health hazards. The selection of suitable alternatives should be determined based on specific needs and material characteristics.
