Halogen-free flame retardants play an important role in the transportation sector. As vehicle design continues to advance and plastic materials become more widely used, flame retardant properties become a critical consideration. Halogen-free flame retardant is a compound that does not contain halogen elements such as chlorine and bromine and has excellent flame retardant effect. In transportation, plastic materials are widely used, such as car interior accessories, electronic device casings, etc. However, plastics often have poor burning properties and can easily cause fire accidents. Therefore, flame retardants need to be added to improve the flame retardant properties of plastics and ensure traffic safety. Special emphasis should be placed on ammonium polyphosphate (APP). As a commonly used halogen-free flame retardant, APP plays a key role in plastic flame retardancy. APP can chemically react with the plastic substrate to form a dense carbonization layer, which effectively isolates the transfer of oxygen and heat, slows down the burning rate and prevents the spread of fire. At the same time, substances such as phosphoric acid and water vapor released by APP can also inhibit combustion and further improve the flame retardant properties of plastics. By adding halogen-free flame retardants such as ammonium polyphosphate, plastic materials in vehicles can obtain good flame retardant properties and reduce the occurrence of fire accidents. Further improve the safety and reliability of transportation. As the requirements for environmental protection increase, the application prospects of halogen-free flame retardants will become broader.
