What are the common categories of flame retardant additives

Jun 19, 2019

Magnesium hydroxide and aluminum hydroxide can be used separately as flame retardant additives, but the amount of addition is large, which is often equivalent to the amount of resin. Inorganic phosphorus is commonly used in red phosphorus and sulfate. Pure red phosphorus is micronized before and after use. It can be used alone or in combination. Phosphate has ammonium phosphate and ammonium nitrate. 

Boron-based flame retardant materials are commonly used hydrated zinc borate, which is generally used in combination with other flame retardant materials. Other metal compounds, such as metal aluminides, metal irons, etc., are mainly used for soot. The organic halide is mainly a bromide, and commonly used are decabromobiphenyl acid, tetrabromobisphenol A, brominated polystyrene, and the like. Chloride is only available in chlorinated paraffin and chlorinated polyethylene. Halides are often used in conjunction with antimony trioxide or phosphide.
