Phosphorus has flame retardancy. Some phosphorus compounds can be used as flame retardants. Phosphorus (chemical name red phosphorus or red phosphorus) contains 100% phosphorus, so red phosphorus is the most effective flame retardant. The mechanism of Red Phosphorus Flame retardancy involves very complex chemical reactions. The simple substance phosphorus is rapidly oxidized to phosphorus oxide, phosphoric acid, polyphosphoric acid and so on under high temperature (aerobic combustion) , sTRONG ACIDIC HIGH-TEMPERATURE MELT can promote material dehydration, carbonization, the formation of a multi-divided layer on the surface of the object, heat insulation, oxygen insulation, reduce the melt temperature, reduce the degradation rate of high polymer, break off oxygen and combustion free radical bond, combined way, for self-extinguishing purposes. Ordinary red phosphorus powder or red phosphorus master batch has become a common flame retardant, but there are very large safety risks,
