不同种类的含磷添加剂和反应性阻燃剂作为各种聚合物材料和应用的无卤替代品越来越成功。磷可以通过增强炭化、产生膨胀或通过无机玻璃形成而在凝聚相中起作用;并且可以通过火焰抑制而在气相中起作用。发生和效率不仅取决于阻燃剂本身，还取决于其与热解聚合物材料和添加剂的相互作用。阻燃性对阻燃剂的改性、增效剂/助剂的使用以及聚合物材料的变化敏感。详细的了解有助于启动量身定制和有针对性的开发。
Different kinds of additive and reactive flame retardants containing phosphorus are increasingly successful as halogen-free alternatives for various polymeric materials and applications. Phosphorus can act in the condensed phase by enhancing charring, yielding intumescence, or through inorganic glass formation; and in the gas phase through flame inhibition. Occurrence and efficiency depend, not only on the flame retardant itself, but also on its interaction with pyrolysing polymeric material and additives. Flame retardancy is sensitive to modification of the flame retardant, the use of synergists/adjuvants, and changes to the polymeric material. A detailed understanding facilitates the launch of tailored and targeted development.
