Why add ATH or MDH to PE and EVA?

Since the discovery of high polymer and its production and application, it has brought a lot of convenience to human life. For molecular weight of polyethylene (PE) and symmetric structure makes it have a certain flexibility and crystallinity, thus being widely used in industry and life, such as architecture, aerospace, automotive, telecommunications, wire and cable, and other fields, but due to the presence of carbon and hydrogen elements of PE, makes it easy to burning polymer, and can produce a large amount of heat in the process of burning, smoke, carbon monoxide and carbon dioxide gas, sustained burns out a long time not easy and often accompanied by drop phenomenon occurs, it is easy to cause fire, very dangerous to people's property and lives. The flammability of PE and ethylene-vinyl acetate copolymer (EVA) seriously restricts their use, so it is particularly important to prepare flame retardant composite materials, and it is necessary to develop high efficiency flame retardant materials with low smoke and toxicity.
