Have, inorganic flame retardant

Inorganic PVC flame retardant materials
Antimony trioxide. Must be used in conjunction with organic flame retardant material.
Magnesium hydroxide, aluminum hydroxide. Can be used separately, but adding large, often a considerable amount of the resin.
Inorganic phosphorus. Common red phosphorus and sulfate, before use of pure red phosphorus and finally through the micro-processing, can be used alone and combination, there ammonium phosphate, ammonium nitrate.
Boron-based flame retardant materials. Top hydrated zinc borate, generally used in conjunction with other flame-retardant materials. Other metal oxides, such as aluminum compounds, iron compounds such as metal, mainly used in smoke.
Organic flame retardant material
Organic halides. Mainly bromide, commonly used, decabromobiphenyl acid, tetrabromobisphenol, brominated polystyrene. Chloride, chlorinated polyethylene get together only paraffin application. Halides often used in conjunction with antimony trioxide or phosphide.
Organic phosphorus compounds. Inorganic phosphorus (V) can be divided into two types of halogenated phosphorus. Halogen-free phosphorus mainly for categories such as triphenyl phosphate, and so on. Halogen-free phosphorus and phosphorus halides to be joined together. Phosphorus halide in the molecule containing both phosphorus and halogen two elements, a synergistic effect intramolecular, which can be used alone,

Common species such as trichlorethylene. ③ nitrogen system. There are three main varieties of poly-nitrogen and ammonia, commonly used in PA and PU in collaboration with the use of phosphorus-based flame retardants.
