Flame retardant PP is a fire-resistant polymer based on Polypropylene. The additives for flame retardant PP and fire-resistant PP plastics are mainly phosphorus compounds and metal hydroxides. The fire-resistant PP material in PP reaches UL94 V-0 level. Copolymer PP, due to its ethylene content in its structure, toughens and makes the structure of propylene no longer regular, which also affects the flame retardant effect. The amount added will also vary depending on the grade of the copolymer PP, It should be pointed out that the current flame retardant has no dripping effect on the co polypropylene flame retardant. At this time, flame retardant polypropylene materials should be used, which can be divided into the following five categories: halogen antimony system polypropylene, that is, gas-phase flame retardant mechanism, using brominated alkyl phosphate ester to treat PP polypropylene. This type of flame retardant also has PBr synergistic effect, making the flame retardant effect significant. At the same time, it can also improve the rheological and processing properties of PP, and has little impact on the physical and mechanical properties of PP. The application of flame retardant PP materials is very extensive. Firstly, in the field of construction, flame-retardant PP materials can be used for building materials such as walls, roofs, and floors, improving the fire safety of buildings. Secondly, in the field of electronics, flame-retardant PP materials can be used as insulation materials for wires and cables, effectively preventing accidents caused by ignition of wires and cables. Finally, in the field of electricity, flame-retardant PP materials can be used for the casing of power equipment Polypropylene General Grade PolystyrenePolyamide
